Figure 2: Recombinant SARS-CoV-2 Spike Protein (B.1.351 Variant) (Functional) (A269990)
Recombinant SARS-CoV-2 Spike Protein (B.1.351 Variant) (Functional) was immobilised on 96-well plates as the capture antigen. Human serum samples from a serological verification panel containing Anti-SARS-CoV-2 Antibodies from National Institute of Biological Standards and Controls, NIBSC (20/B770), were added to the plate for incubation and subsequent washing. Secondary Anti-Human IgG Antibodies (HRP) were added for detection in a sandwich ELISA format. The final colorimetric reaction occurs upon addition of TMB substrate which is quenched by the addition of acid solution.
