ELISA is a technique used to detect antibodies or antigens in a sample. It works by first adding antigens to wells which antibodies then bind to. Secondary antibodies with an enzyme are then added, and if the antigens and primary antibodies are present, the enzyme causes a color change reaction. This process allows ELISA to be used to test for conditions like HIV in patients by simulating the immune response in a lab setting.

Monoclonal antibodies anticancer therapy[1] (1)
Monoclonal antibodies (mAbs) are identical antibodies produced by a single clone of immune cells that recognize a specific antigen. There are three main mechanisms by which mAbs can treat cancer: 1) directly inducing apoptosis or inhibiting growth of cancer cells by binding to antigens, 2) delivering toxins, radioisotopes or cytokines to cancer cells when modified for drug delivery, and 3) using bispecific antibodies to bind cancer antigens and effector cells to elicit an immune response. Common mAbs approved by the FDA for cancer treatment target growth factor receptors or directly elicit apoptotic signaling in cancer cells. Production of mAbs is primarily through hybridoma technology fusing antibody-producing cells with myeloma cells.

Factors that can drive degradation include formulation, storage conditions, manufacturing processes, and surface interactions. Examples of degradation include bevacizumab aggregation due to silicon, surfactant, agitation, storage devices, and
Monoclonal Antibodies and their role in Pharmacology
Monoclonal antibodies (mAbs) are monospecific antibodies produced by a single clone of cells. They have specific structures and functions that allow them to recognize antigens and induce immune responses. mAbs are produced using hybridoma technology and have evolved from murine to humanized and human forms to reduce immunogenicity. They are used widely in treatment of diseases like cancer, autoimmune disorders, transplant rejection and infections.
Sustainable fashion short
Sustainable fashion aims to create environmentally friendly and socially responsible systems. Conventional clothing production can harm the environment through water pollution from pesticides and dyes, emissions from synthetic fibers and transportation, and filling landfills when clothes are discarded. Materials like modal rayon are made from processed beechwood but can release formaldehyde and cause allergic reactions in some people. Fur farming produces animal waste that pollutes waterways with nitrogen and phosphorus while processing involves harmful chemicals. Garment manufacturing has issues with long hours, unsafe conditions, harassment, restrictions on unions and supply chain pressures that can compromise working standards. Alternatives promote fair trade, child labor-free and eco-friendly options.
Monoclonal antibody
Monoclonal antibodies (mAbs) have various applications including diagnostic, therapeutic, and catalytic uses. Diagnostically, mAbs are used in pregnancy tests, disease diagnostics, and immunohistochemistry. Therapeutically, mAbs treat cancer, transplant rejection, and autoimmune diseases by mechanisms like enhancing immune response, blocking growth signals, inhibiting angiogenesis or cytokines. Some FDA-approved mAbs for cancer include rituximab, trastuzumab, and bevacizumab. Conjugated mAbs can deliver toxins or radiation directly to tumors. mAbs also have applications in areas like organ transplantation, autoimmune diseases, and drug targeting.

1 elisa technique
ELISA (Enzyme-Linked Immunosorbent Assay) is a biochemical technique used to detect antibodies or antigens in a sample. There are three main types of ELISA: competitive ELISA where a labeled antigen competes for antibody binding sites; sandwich ELISA where antibodies coat a surface to detect a specific antigen; and indirect ELISA where a test antigen is coated on a surface and secondary antibodies are used to detect primary antibodies in a serum sample. The amount of color change produced corresponds to the concentration of antigen or antibody in the original sample.
Immunological assays (RIA &ELISA)
This document discusses immunoassays and two common types - radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA). RIA was developed in the 1950s and involves competition between labeled and unlabeled antigens for binding with antibodies. Radioactivity of the antigen-antibody complex is then measured. ELISA uses an enzyme like alkaline phosphate to visualize antigen-antibody reactions. It has two types - direct ELISA using a double antibody sandwich and indirect ELISA using direct antigen coating. Both assays are used to detect various antigens and antibodies and have applications in clinical diagnosis, food testing, and toxicology.
Immunological assay
This document discusses two types of immunoassays: radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA). RIA was developed in the 1950s and involves competition between labeled and unlabeled antigens for binding with antibodies. The amount of radioactivity measured corresponds to antigen concentration. ELISA is commonly used for initial HIV screening and has advantages over RIA by not requiring radioactive materials. ELISA uses an enzyme-linked antibody for detection and can be performed as either a direct or indirect assay. Both methods have various applications for detecting proteins, antibodies, drugs, and diagnosing infections.

Biofuel: Enzyme Kinetics
Enzymes accelerate biological reactions and their reaction rates depend on conditions like temperature and pH levels. The workshop explored how altering conditions affected catalysis and reaction rates using the enzyme p-nitrophenyl glucopyranoside. Experiments showed this enzyme works best at pH 5, where it hydrolyzes starch into glucose and p-nitrophenol, detected by its yellow color. Samples tested at different pH levels found only pH 5 turned yellow, and spectrometer readings confirmed more products formed at lower pH, demonstrating pH significantly impacts the enzyme's reaction rate.
Got protein?
The workshop tested the protein content of different types of milk using the Bradford Protein Assay. Samples of different milks were diluted and added to Coomassie blue dye, which binds to amino acids and changes color based on protein concentration. Known protein standards were also prepared. Absorbance measurements from a spectrophotometer were used to create a standard curve to calculate the exact protein concentration in mg/mL of the milk samples.
pGLO Bacterial Transformation and pGLO SDS Page Extension
Bacterial transformation involves inserting a gene from one organism into another using plasmids. Plasmids containing a gene of interest are introduced into bacteria, allowing the bacteria to express proteins from that gene. In this workshop, green fluorescent protein (GFP) was used as a marker to test if E. coli bacteria were transformed. E. coli cultures were grown, one containing a GFP plasmid. Under UV light, the plasmid-containing culture showed GFP expression, indicating transformation occurred. SDS-PAGE was used to separate and observe the transformed bacteria's proteins, revealing bands corresponding to GFP.
Nanotechnology
The workshop covered nanotechnology, which involves working with materials smaller than 100 nm. At this scale, materials exhibit different physical, chemical, and biological properties that can be exploited for various applications. For example, nanomaterials have more surface area, inducing more catalytic reactions and reactivity. The workshop demonstrated creating a hydrogen sensor using electrospun polyethylene oxide fibers coated with palladium and gold through sputtering to detect hydrogen concentrations.
Bioinformatics
Bioinformatics applies statistics and computer science to molecular biology, mapping and analyzing DNA and protein sequences and comparing sequences between organisms. The workshop taught how bioinformatics is used in scientific investigations by allowing easy access to known data. Participants practiced using bioinformatics databases to find DNA sequences for fibrinogen alpha chains across species, translate DNA to protein sequences, and compare protein sequences between species to understand how bioinformatics works.
Genetic Modification in Papaya and Fritos® Corn Chips
The document summarizes an experiment testing genetically modified organisms (GMOs) in papaya and Fritos corn chips. DNA was extracted from the samples and tested using PCR and gel electrophoresis. The results initially showed no GMO DNA sequences in the papaya or corn chips. However, the results were deemed unreliable due to DNA degradation. The experiment would need to be repeated to obtain more reliable conclusions about the presence of GMOs in the food samples.
Genetic Modification in Maize, Papaya, Fritos® Corn Chips, and Natura® Soymilk
This document summarizes an experiment to identify GMO genes in corn, soy milk, and papaya samples. DNA was extracted from the samples and amplified via PCR with primers for the 35S promoter, NOS terminator, and PSII genes. The resulting DNA fragments were run on an agarose gel during electrophoresis. Bands were observed at the expected sizes for the 35S and NOS genes in the corn and papaya samples, indicating they contain those GMO genes, but not in the soy milk sample. The results suggest the corn and papaya samples contain GMOs while the soy milk does not, but the experiment needs to be repeated to obtain reliable conclusions due to potential human errors.
Review Paper 1
This review paper summarizes research on the effects of cell phone electromagnetic radiation exposure on the brain. Several studies found associations between long-term cell phone use (>10 years) and brain tumor development, especially on the side of the head most used. Exposure has been shown to up-regulate cell death pathways in neurons and affect neural function in humans. It may also cause oxidative damage to neuronal mitochondrial DNA and alter blood-brain barrier permeability. Additionally, cell phone radiation was found to change the oxygen affinity and structure of hemoglobin as well as disrupt inter-hemispheric brain synchronization. While some studies found no effects, overall the review indicates that cell phone use may pose brain-related health risks.
Annotated bibliography #2
This study investigated whether exposure to cell phone radiation up-regulates (increases) genes related to apoptosis in primary cultures of neurons and astrocytes. The researchers exposed cultures of neurons and astrocytes to cell phone radiation for 2 hours. Gene expression analysis found increased expression of caspase-2, caspase-6, and Asc apoptosis genes in both neurons and astrocytes exposed to the radiation. The study concluded that even short-term exposure to cell phone radiation can increase expression of genes involved in apoptosis pathways and cause cell death in brain cells, with neurons appearing more sensitive than astrocytes.

Annotated bibliography #3
Seyed et al. investigated the effects of mobile phone radiofrequency electromagnetic fields (EMFs) at 910 MHz and 940 MHz on the structure and function of hemoglobin. They found that exposure to EMFs altered hemoglobin's oxygen affinity and tertiary structure by decreasing its ability to bind oxygen in the lungs and increasing its release of oxygen to tissues. The changes corresponded to the intensity and duration of EMF exposure, suggesting that EMFs could affect human respiration.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

ELISA
- 1. ELISA Workshop By Ricardo Chiesa ELISA is a technique used in immunology for the detection of an antibody or antigen in a sample. An antigen is a molecule or substance that enters the body and is recognized as a foreign material. As a result, it promotes the production of an antibody that will bind to the antigen and neutralize it, avoiding any type of infection for the organism. This process is known as immunization. In the lab, ELISA was done to simulate the test and diagnose of HIV in patients. First, the antigens were added to the cells of a microplate strip in order for them bind to the surface. In this case, chicken gamma-globulin (purified from egg yolks) was used as an antigen representative. After the wells were washed with detergent, the primary antibodies (polyclonal rabbit antibodies) were added and they were supposed to bind to the antigens, if there were any. Then, the secondary antibodies are added, and they were supposed to bind to the primary antibodies. These secondary antibodies were obtained from goats by injecting rabbit’s antibodies into them. As a result, rabbit’s antibodies were recognized by the goat’s immune system as antigens, so antibodies were produced. Finally, the detection of secondary antibodies involves an enzyme- substrate reaction. These antibodies contained an HRP enzyme bound to them that in the presence of nitrogen peroxide will catalyze the oxidation of a substrate known as TMB, and will produce a blue color. In the experiment, the substrate was added to the wells and oxidation occurred in some of the wells.
