Anti-SARS-CoV-2 (B.1.1.7) Antibody IgG Titer Serologic Assay Kit (Spike RBD) | RAS-T026 | Acro Biosystems | SARS-CoV-2 Antibody Titer Assay Kits
Multiple variants of SARS-CoV-2 are circulating globally and posting new challenges to human health. The variant B.1.1.7 identified in the United Kingdom (UK) carries a large number of mutations and is reported to spread more easily and quickly than other variants. The variant B.1.351 identified in South Africa and P.1 identified in Brazil show evidence of increased transmissibility and resistance to established immunity. A common mutation identified in the U.K., South African and Brazilian variants is N501Y, which resides on the receptor-binding domain (RBD) of SARS-CoV-2 spike protein. To evaluate the impacts of the new variants, a rapid and effective assay kit detecting the levels of antibody against the mutant is in urgent need.
This kit is developed for serologic test for IgG titer of Anti-SARS-CoV-2 Spike RBD antibody in serum/plasma in vitro. The Spike RBD antigen used in this kit contains the N501Y mutation found in the U.K. variant (known as B.1.1.7, 20B/501Y.V1 or VOC 202012/01), the South African variant (known as B.1.351 or 20C/501Y.V2) and the Brazilian variant (known as P.1).
It is for research use only.

This assay kit employs a standard indirect-ELISA format, providing a rapid detection of Anti-SARS-CoV-2 antibodies in serum by SARS-CoV-2 Spike RBD. The kit consists of Pre-coated SARS-CoV-2 Spike RBD Microplate, an Positive Control, an Negative Control, an HRP-Anti-Human IgG secondary antibody and related buffer.
Your experiment will include 4 simple steps:
a) Add your sample to the plate. The samples and Control sample are diluted by Dilution Buffer.
b) Add diluted Secondary antibody HRP-Anti-Human IgG to the plate. The Secondary antibody is diluted by Dilution Buffer.
c) Wash the plate and add TMB or other colorimetric HRP substrate.
d) Stop the substrate reaction by add diluted acid. Absorbance (OD) is calculated as the absorbance at 450 nm minus the absorbance at 650 nm to remove background prior to statistical analysis. The OD Value reflects the amount of antibody bound.
