Validation of anti niv igm capture elisa version#1krishgen
NiV is a negative-sense, non-segmented RNA virus that was first isolated from cerebrospinal fluid of human patients and classified in the family Paramyxoviridae under the new genus
Henipavirus. Its genome encodes six structural proteins: the nucleocapsid (N) protein,
phosphoprotein (P), matrix (M) protein, fusion (F) protein, glycoprotein (G), and large (L)
protein.
Nipah virus glycoprotein G has a globular head domain formed of a six-bladed beta sheet propeller, connected via a flexible stalk domain to a transmembrane anchor. The G binds to the cellular receptors ephrin B2 are ephrin B3, mediating viral attachment. Following attachment Nipah Virus glycoprotein G undergoes a conformational change that leads to triggering of glycoprotein F which leads to membrane fusion (Biering et al, 2012).
The Nipah virus glycoprotein G is a recombinant protein expressed in mammalian HEK293 cells. It is presented as a fusion protein with a mouse Fc tag linked to the C-terminus of glycoprotein G, amino acids 71-602.
We established preliminary specifications defining acceptable ranges for the parameters indicated herein below for our Anti Nipah Virus IgM Capture ELISA kit. These parameters were tracked day-to-day, run-to-run, and operator-to-operator, over a schedule defined inhouse.
Recommended assay characteristics included absorbance of a zero concentration standard; factors which describe the calibration for each standard and statistical description of the calibration curve such as coefficient of correlation, slope and/or intercept; and recovery of results on control samples. It is important to be able to relate the specifications for a parameter to expected reliability of the result. Our in-house standard defined was r=0.990.

White Paper : Need for Standardization of Tests for Plant Viruseskrishgen
The document discusses the need to standardize virus testing procedures for tissue culture plants in India. Currently, each accredited testing laboratory uses its own in-house assays and methods, leading to inconsistent results. The author proposes that the Department of Biotechnology accredit standardized virus testing kits from commercial Indian manufacturers to be used uniformly across all testing laboratories. This would ensure a transparent, reproducible certification process and boost confidence among stakeholders in the tissue culture industry.

This slide is very helpful for physiotherapy students and also for other medical and healthcare students.
Here is the summary of hypotension:
Hypotension, or low blood pressure, is when the pressure of blood circulating in the body is lower than normal or expected. It's only a problem if it negatively impacts the body and causes symptoms. Normal blood pressure is usually between 90/60 mmHg and 120/80 mmHg, but pressures below 90/60 are generally considered hypotensive.

ATEZOLIZUMAB -
PD-L1 BLOCKER DRUG
Drug Class: Monoclonal Antibod-
ies; PD-L1 Blocker
Atezolizumab is an Fc-engineered,
humanised immunoglobulin G1 (IgG1)
monoclonal antibody that directly binds
to PD-L1 and provides a dual blockade
of the PD-1 and B7.1 receptors, re-
leasing PD-L1/PD-1 mediated inhibi-
tion of the immune response, including
reactivating the anti-tumour immune
response without inducing antibody-
dependent cellular cytotoxicity.
Atezolizumab spares the PD-L2/PD-1
interaction allowing PD-L2/PD-1 medi-
ated inhibitory signals to persist.
Atezolizumab as monotherapy is indi-
cated for the treatment of adult pa-
tients with locally advanced or meta-
static urothelial carcinoma (UC):
• after prior platinum-containing chem-
otherapy, or
• who are considered cisplatin ineligi-
ble, and whose tumours have a PD-L1
expression ≥ 5%.
Atezolizumab is also indicated for the
treatment of adult patients with locally
advanced or metastatic non-small cell
lung cancer (NSCLC) after prior chem-
otherapy. Patients with EGFR activat-
ing mutations or ALK-positive tumour
mutations should also have received
targeted therapy before receiving Ate-
zolizumab.

Pharmacokinetics
Serum samples for PK analyses were collected at Cycle 1, Days 1 (before infusion, 30 ± 30 min after infusion), 2 (24 ± 6 h
after infusion), 4 (72 ± 12 h after infusion), 8 (± 1 day), 15 (± 1 day), and 22 (± 1 day); Cycles 2, 3, and 4, Days 1 (30 ± 30 min
after infusion) and 22 (± 1 day); Cycles 5 and 7, Day 1 (30 ± 30 min after infusion); and Cycle 6 onward, Day 22 of even-
numbered cycles (± 1 day). The blood samples were centrifuged at 1500 to 2000×g for 15 min at 4 °C. The serum samples
were then stored at −70 °C or less. The concentrations of atezolizumab in human serum were measured using ELISA, with
the lower limit of quantification of 60 ng/mL.
KRIBIOLISA™ ATEZOLIZUMAB ELISA
The method employs the quantitative sandwich enzyme immunoassay technique. Antibodies to Atezolizumab are pre-coated onto mi-
crowells. Samples and standards are pipetted into microwells and human Atezolizumab present in the sample are bound by the capture
antibody. Then, a HRP (horseradish peroxidase) conjugated anti-Atezolizumab antibody is pipetted and incubated. After washing mi-
crowells in order to remove any non-specific binding, the ready to use substrate solution (TMB) is added to microwells and color devel-
ops proportionally to the amount of Atezolizumab in the sample. Color development is then stopped by addition of stop solution. Ab-
sorbance is measured at 450 nm.
KRIBIOLISA™ ANTI-ATEZOLIZUMAB ELISA
The method employs the competitive enzyme immunoassay technique. Atezolizumab is pre-coated onto microwells. Samples or stand-
ards along with the tracer are pipetted into microwells and antibodies to Atezolizumab present in the standards or sample will compete
with tracer and bound by the capture antibody. After washing microwells, HRP conjugate is pipetted and incubated. Free HRP conju-
gate will be removed by washing cycle. The ready to use substrate solution (TMB) is added to microwells and color develops inversely
proportionally to the amount of Anti-Atezolizumab present in the sample. Color development is then stopped by addition of stop solu-
tion. Absorbance is measured at 450 nm.
