IgG antibodies from serum / plasma of human will bind to the SARS CoV-2 virus whole cell antigen coated on to the Microtitre plate (ELISA wells). In the next step, anti Human IgG HRP binds to captured human IgG antibodies. Subsequently, chromogenic substrate (TMB/H2O2) is added, the reaction is stopped by 1N H2SO4. The intensity of color / optical density is measured at 450 nm. The kit is for in- vitro use for monitoring anti-SARS CoV-2 IgG antibodies in human only.
