Simplification of Fed-Batch Processes Using Modified Amino AcidsMerck Life Sciences
Mammalian fed-batch processes to produce biopharmaceuticals, e.g. monoclonal antibodies (mAbs), rely on strategic feeding of nutrients aiming at cell culture longevity and protein yield. At high concentrations and neutral pH, limitations in these bioprocesses arise from the low solubility or stability of some compounds, predominantly amino acids. In current processes, L-cysteine and L-tyrosine are fed separately at alkaline pH, resulting in pH peaks and precipitations. To simplify next generation processes, both amino acids have been chemically modified to enhance their respective stability and solubility profiles.
CHO fed-batch processes were substituted with the derivatives phosphotyrosine di-sodium salt (PTyr) and S-sulfocysteine sodium salt (SSC). Cellular performance as well as stability of the single substances in neutral pH feed were assessed. Lastly, the suitability of modified amino acids in fed-batch processes was confirmed examining critical quality attributes of the produced mAb.
In feed, PTyr solubility was evaluated at 70 g/L with a stability of at least 6 months stored light protected at 4 °C. The derivative was not impacting cellular performance or product quality. In cell culture supernatant, PTyr cleavage was induced by released phosphatases, thus being bioavailable for the cells.
SSC was demonstrated stable for at least 3 months in feed stored light protected at RT. In fed-batch processes, integrating the derivative into the main feed, cell specific productivity was significantly improved compared to the two-feed system. Further, IgG heterogeneity was decreased by reduced fragmentation and trisulfide bond formation of the antibody. Finally, the mechanism of action of SSC was investigated and results pointed out to an anti-oxidative response mediated through an increase in superoxide dismutase enzymes and in total intracellular glutathione pool involved in ROS elimination.
In addition to the simplification of fed-batch processes via the implementation of a single feed strategy, the two derivatives also enable the production of highly concentrated and room temperature stable feeds along with optimized space time yields.
In this webinar you will learn:
• Design of highly concentrated and stable feeds.
• Overcoming issues with unstable or insoluble amino acids.
• Understanding the function of modified amino acids in cellular metabolism and antibody production.

Process Intensification for future bioprocessingMilliporeSigma
Watch the interactive recording here: https://bit.ly/2OdLYwX
Process optimization and upstream intensification led to smaller, more efficient biomanufacturing facilities becoming more commonplace, with smaller facilities comprised primarily of single use or hybrid technology capable of producing significant amounts of drug product. Such changes, however, bring new challenges, like managing the supply of huge amounts of cell culture media or buffers within smaller footprints. In this webinar two topics will be addressed that help to intensify upstream and downstream processes and address the challenges of future facilities.
Bulk powders of cell culture media (CCM) or single chemicals often show physical disadvantages. CCM powders with fine particles show high dust formation and poor flowability. In addition, dissolution is time consuming due to floating of light particles on the water surface. For the pursued intensification of upstream processing, media preparation times are becoming a serious bottleneck. This mainly accounts for the much higher media consumption or higher concentrated media formulations for future continuous upstream processes. Granulated material can overcome limitations with CCM powder, while additionally being a viable option to reduce caking of bulk chemicals like buffers.
Buffer production for downstream processing remains a significant portion of the facility footprint, labor needs and equipment cost. As downstream operations are essentially product-mass-based, increased productivity in upstream will lead to a proportional increase in demand for downstream buffers. Merck KGaA Darmstadt, Germanty R&D has their expertise in concentration of buffers to improve and streamline buffer management.

The Viscosity Reduction Platform: Enabling Subcutaneous (subQ) DeliveryMerck Life Sciences
Watch the presentation of this webinar here: https://bit.ly/3FKGUH6
At the high protein concentrations required for subcutaneous administration, protein formulations often become highly viscous. In this webinar, Dr. Tobias Rosenkranz will introduce a new approach that combines different excipients to reduce viscosity and discuss synergistic effects.
Subcutaneous (subQ) administration can improve patient convenience and reduce healthcare costs by avoiding the need for hospitalization. Yet in some cases, high protein concentrations make formulations far more viscous, prohibiting this route of administration. While viscosity can normally be reduced by using certain excipients, merely adding more and more of a single excipient may not bring sufficient improvement and can even compromise protein stability. This webinar will introduce an excipient platform that makes it possible to combine excipients in ways that can reduce protein viscosity to a greater extent.
In this webinar, you will learn about:
• Challenges arising from high concentrated protein formulations
• The viscosity reduction platform: a portfolio of excipients to manage protein viscosity

Access the interactive recording: https://bit.ly/35vWeoD
Abstract:
Downstream processing of monoclonal antibodies and other recombinant proteins requires large volumes of buffer to maintain pH and conductivity during chromatographic and ultrafiltration operations. A typical process requires more than 5 L of buffer in downstream purification operations for each liter of cell culture processed. The preparation of these buffers requires a large footprint for ‘buffer farms’ with mixing tanks, filtration equipment and storage tanks to meet the continuous demand for buffers for an overall facility. This has been cited as a bottleneck by many manufacturing facilities.
The ability to outsource or implement a streamlined buffer preparation step has numerous benefits including reduced capital, labor, floor space, raw materials inventory, facility overhead and QC testing and release. With these benefits come some risks that pharmaceutical manufacturers must address before implementing a new buffer preparation strategy for these critical raw materials that are fundamental to manufacturing. These risks include raw material variability, accuracy of the buffer specifications, as well as stability and quality of the buffer upon transport and over time.
In this webinar, you will learn:
- How to implement and benefit from an integrated buffer delivery platform
- How to ensure quality and accuracy of the buffers using risk-mitigation and cost modelling

Facility Intensification and Cost Reduction using an Integrated Buffer Delive...Merck Life Sciences
Access the interactive recording: https://bit.ly/35vWeoD
Abstract:
Downstream processing of monoclonal antibodies and other recombinant proteins requires large volumes of buffer to maintain pH and conductivity during chromatographic and ultrafiltration operations. A typical process requires more than 5 L of buffer in downstream purification operations for each liter of cell culture processed. The preparation of these buffers requires a large footprint for ‘buffer farms’ with mixing tanks, filtration equipment and storage tanks to meet the continuous demand for buffers for an overall facility. This has been cited as a bottleneck by many manufacturing facilities.
The ability to outsource or implement a streamlined buffer preparation step has numerous benefits including reduced capital, labor, floor space, raw materials inventory, facility overhead and QC testing and release. With these benefits come some risks that pharmaceutical manufacturers must address before implementing a new buffer preparation strategy for these critical raw materials that are fundamental to manufacturing. These risks include raw material variability, accuracy of the buffer specifications, as well as stability and quality of the buffer upon transport and over time.
In this webinar, you will learn:
- How to implement and benefit from an integrated buffer delivery platform
- How to ensure quality and accuracy of the buffers using risk-mitigation and cost modelling

Protein viscosity is a major challenge in preparing highly concentrated protein formulations suitable for subcutaneous injection. Recently, the Viscosity Reduction Platform (VRP) was introduced and its technical key features and benefits for formulations were discussed. However, highly viscous solutions do not only pose a challenge when administering a drug to a patient, they can also impose technical limitations in the manufacturing process.

Use of Excipients in Downstream Processing to Improve Protein PurificationMilliporeSigma
Excipients are used to improve the stability of protein-based therapeutics by protecting the protein against a range of stress conditions such as temperature changes, pH changes, or agitation. Similar stresses are applied to proteins during downstream purification. Shifts in pH during Protein A chromatography, subsequent incubations at low pH for virus inactivation, and changes in conductivity in ion exchange chromatography can lead to aggregation, fragmentation, or other chemical modifications of the therapeutic protein. Given the potential impact on the protein’s structural integrity, there is a need for approaches to reduce the risk presented by the conditions during downstream processing. For example, integration of a solution to prevent aggregation of proteins would be a more efficient strategy than implementing steps to remove multimeric forms.
This white paper highlights the results from a recent paper by Stange et. al., in which protein stabilizing excipients such as polyols, sugars, and polyethylene glycol (PEG4000) were used as buffer system additives. Effect of the excipients on elution patterns, stabilization of the monomer antibody, host-cell protein removal, virus inactivation rates and binding capacity of cation exchange chromatography were explored.
Exploring the protein stabilizing capability of surfactants against agitation...MilliporeSigma
Agitation of therapeutic protein solutions during manufacturing, shipping and handling is one of the major initiators for protein aggregation and particle formation during the life history of a protein drug. Adsorption of protein molecules to liquid-air interfaces leads to the formation of highly concentrated protein surface films. The rupture of these protein films due to various mechanical processes can then result in the appearance of protein aggregates and particles in the bulk solution phase.
One technique to stabilize proteins against stress induced by liquid-air interfaces is the use of non-ionic surfactants. About 91% of antibody formulations commercially available in 2021 contained a surfactant. Polysorbate 20 and 80, composed of a hydrophilic polyoxyethylene sorbitan and hydrophobic fatty acid esters, made up the largest part being employed in 87% of said formulations.
Despite their frequent use in parenteral drug products, concerns have been raised for decades about the application of polysorbates as surfactants in biopharmaceutical formulations. Autoxidation of polysorbate, caused by residual peroxides in polysorbates, can damage the proteins and can further drive the oxidative degradation of polysorbate. Chemical and enzymatic hydrolysis of polysorbate may lead to the formation of free fatty acid particles, which may become visible; and both mechanisms eventually lead to the reduction in polysorbate concentration. Therefore, the purpose of the current study was to compare various molecules for their capabilities to reduced agitation-induced protein aggregation and particle formation; and furthermore, investigate their underlying protein stabilizing mechanisms.

Watch the presentation of this webinar: https://bit.ly/3Pjpjvr
Highlights of this webinar:
- Surface plasmon resonance as a powerful tool for biologic characterization including mAbs and ADCs.
- SPR allows rapid binding analysis in real time without using labels for SARS-CoV-2 receptor binding domain mutations.
- Kinetic data is indicative of possible neutralizing activity allowed assessment of neutralizing ability of therapeutic monoclonal antibodies.
- The application can provide preliminarily efficacy information and facilitated mAbs/ACDs candidate selection process
Detailed description:
Characterization of therapeutic monoclonal antibodies (mAbs) or Antibody drug conjugates (ADCs) is challenging due to their ability to bind to a variety of proteins via their Fc and Fab domains, giving rise to diverse biological functions associated with each domain. The Fc domain of mAbs interacts with Fc receptors with varying affinities, which can influence biological processes such as Complement-dependent cytotoxicity (CDC) and Antibody-dependent cellular cytotoxicity (ADCC), transcytosis, phagocytosis, and/or serum half-life.
An important characteristic of an antibody is its Fc effector function. Antibodies can be engineered to obtain desired binding of the Fc region to Fc receptors expressed on effector cells. Hence, it is crucial to evaluate the binding interaction of mAbs/ADC with Fc receptors in the early phase of drug development to understand the potential biological activity of the product in vivo.
Surface Plasmon Resonance (SPR) is a powerful technique to establish binding kinetics in real-time, label free, and high sensitivity with low sample consumption. Along with target antigen binding, it is crucial to evaluate the binding interaction of antibodies and ADCs with Fc receptors. Our SPR case studies investigated the impact on binding kinetics of ADCs with different linkers and the binding interactions of SARS-CoV-2 spike protein variants and evaluated the neutralizing ability of therapeutic mAbs. SPR characterisation can be facilitated in all stages of the product life cycle to ensure the quality and safety of mAbs and ADCs.

Improve Operational Efficiency by Over 30% with Product, Process, & Systems A...MilliporeSigma
Watch the presentation of this webinar here: https://bit.ly/3adaxWh
When implementing new automation systems, organizations must consider things like deployment time, user adoption, and costs.
They must also consider the cost of doing nothing – that is, what competitive advantage is lost in standing still? What time and quality is lost in repetitive, manual tasks rather than an automated, digital workflow? What operational efficiencies are lost?
In this webinar we examine how a product, process, and system agnostic automation platform can be deployed faster than traditional system specific software while bringing greater operational efficiencies (in many cases over 30% improvement).
To remain competitive in the market, biopharma manufacturers must adopt automation and digital technologies, but most plants still have island of automation consisting of independently functioning, standalone unit operations. This results in operational inefficiency, regulatory concerns, and a poor understanding of the process and product life cycle.
Taking the first, right step must include considering risks, costs, timelines, and technology alternatives. Traditional automation approaches tied to specific systems, processes, and products are, by their nature, limited; while an agnostic platform will address current biomanufacturing business challenges and ensure future readiness. With the right platform, a phased automation implementation can yield operational efficiency gains of up to 30% and improved product quality and regulatory compliance.
In this webinar, let's explore:
• Challenges of automation and digital technology adoption
• What a product, process, and system agnostic platform entails
• Applications and benefits of a process orchestration platform
• Ensuring future readiness with process orchestration

Rapid Replication Competent Adenovirus (rRCA) Detection: Accelerate your Lot ...MilliporeSigma
Watch the presentation of this webinar here: https://bit.ly/3MJ4u9V
Testing for presence of replication competent adenovirus (RCA) is a key component to ensure patient safety and a requirement for all biologicals manufactured using adenoviral vectors. For many adenoviral-based products, the RCA assay is a rate-limiting assay for lot release.
Join this webinar to learn about a rapid RCA detection assay currently in development, which combines a 7-day culture assay with a highly sensitive molecular endpoint specific for RCA. The method can detect presence of as little as 1 RCA in adenoviral vector material at an approximate concentration of 5x107 - 2x108 vector particles (VP)/mL, making it a suitable method to meet regulatory requirements while accelerating your lot release timelines.
In this webinar, you will learn about:
• Regulatory framework for adenoviral vector products
• Considerations for lot release testing of adenoviral-based therapies
• Advantages of a rapid method for RCA testing on production lot material

How to Accelerate and Enhance ADC TherapiesMilliporeSigma
In this webinar, you will learn about:
The advantages of using advanced intermediates to develop ADC therapies
How to increase ADC solubility and efficiency
Fast, small-scale ADC library generation
Seamless supply chain with reduced complexity and regulatory support
The ADCore product line offers versatile intermediates that simplify the synthesis of common ADC payloads (dolastatins, maytansinoids, and PBDs) by greatly reducing the number of synthetic steps. This translates to savings in development and manufacturing costs and shorter timelines to the clinic. To address the poor solubility of many ADC payloads, ChetoSensar™ was developed to significantly increase the hydrophilicity of the drug linker, which has been shown to also substantially increase the efficacy of ADCs and broaden the therapeutic window.
Lastly, the ADC Express™ service leverages conjugation chemistry and analytical expertise to help design and quickly synthesize sets of potential ADC therapies suitable for screening to simplify candidate selection and get ADC therapies to market faster.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
