Description：ELISA for quantitative estimation of Anti SARS-CoV-2 IgG antibodies to Spike RBD protein of the Omicron variant in human serum and plasma samples.
The assay kit contains a SARS-CoV-2 Spike RBD Omicron Variant （B.1.1.529） protein Coated Microtiter Plate and Anti-SARS-CoV-2 Spike RBD Antibody （Omicron Reactive） as Standards in the kit.
Why the RBD protein?
The COVID-19 Omicron variant is by far the most divergent variant characterized by a high number of mutations in the spike protein.
Several mutations （e.g., N501Y, P681H） have been identified in previous variants and are associated with increased transmissibility, immune escape, or other properties.
There are a total of 30 amino acid changes： among which 15 are located in the RBD region of the virus.
