49,000.00

ELISA for the Quantitative determination of neutralizing antibody to the SARS-CoV-2 Spike RBD of the Mu variant in serum and plasma samples.

As other Krishgen ELISA, these kits are based on monoclonal antibody detection for better sensitivity. Proprietary stabilizers and blockers for optimal signal:noise ratio, with specific antibodies allow for a robust ELISA. Features include a standard, ready-to-use protocol, and the option to run serum or plasma samples.

Description

Introduction:
The GENLISA ELISA kits are used for assessing the specific biomarker in samples analytes which may be serum, plasma and cell culture supernatant as validated with the kit. The kit employs a blocking ELISA technique which mimics the virus neutralization process.SARS-CoV-2-neutralizing antibodies primarily target the trimeric spike (S) glycoproteins on the viral surface that mediate entry into host cells. The S protein has two functional subunits that mediate cell attachment (the S1 subunit, existing of four core domains S1A through S1D) and fusion of the viral and cellular membrane (the S2 subunit).Potent neutralizing antibodies often target the receptor interaction site in S1, disabling receptor interactions. The spike proteins of SARS-CoV-2 commonly bind to the human angiotensin coverting enzyme 2 (ACE2) protein as a host receptor through their S1B domain. Receptor interaction is known to trigger irreversible conformational changes in coronavirus spike proteins enabling membrane fusion. SARS-CoV-2 initiates an immune response, which leads to the production of antibodies. These neutralizing antibodies provide protection against future infection from SARS-CoV-2 (Variant B.1.621), as they remain in the circulatory system for months to years post infection. SARS-CoV-2 keeps evolving by continual mutation which enables the virus to evade vaccines and immune systems. Some of the mutations, the U.K. variant (B.1.1.7), the Brazil variant (P.1), the South Africa variant (B.1.351), the Indian variant (B.1.617), and the Omicron variant (B.1.1.529) may have allowed the virus to escape from neutralizing antibodies. This Neutralizing Kit works on using Recombinant SARS-CoV-2 (2019-nCoV) Spike RBD Protein and a Neutralizing Antibody sensitive to the variant as a Standard/Calibrator to measure the effective inhibition %.

Intended Use:
The GENLISA SARS-CoV-2 (Covid-19) Mu Neutralizing Antibody (B.1.621) ELISA kit is used as an analytical tool for the qualitative and quantitative detection all types of neutralizing antibodies against SARSCoV-2 spike RBD proteins in serum or plasma.

Principle:
The method employs sandwich ELISA technique. The protein-protein interaction between HRP- SARS-CoV-2 spike RBD and hACE2 can be blocked by neutralizing antibodies against SARS-CoV-2 spike RBD. Samples and controls are pipetted in a blank microtitre plate and incubated with HRP conjugated human SARSCoV-2 spike RBD protein. The antibodies to SARS-CoV-2 present in the samples and controls bind to the SARS-CoV-2 spike RBD protein to form a complex.This solution of bound and unbound antibodies to SARS-CoV-2 Variant (B.1.621) is then pipetted into human ACE2 coated microplate. After washing to remove the bound complex of Anti-SARS-CoV-2 Variant (B.1.621) and HRP conjugated SARS-CoV-2 spike RBD, the substrate solution (TMB) is added to the microwells.Post incubation, color develops proportionally to the amount of unbound Anti-SARS-CoV-2 (Covid-19) Variant B.1.621 present in the sample. Color development is then stopped by addition of stop solution.Absorbance is measured at 450 nm.
