Anti-SARS-CoV-2 (COVID-19) Human IgG Assay Kit is a Quantitative indirect enzyme-linked immunoassay (ELISA) for detection of human IgG antibodies against SARS-CoV-2 (COVID-19) in human serum and plasma samples.

Quantitative determination of Anti-SARS-CoV-2 IgG antibodies is achieved by an indirect ELISA format,

Microwells of the plate are pre-coated with recombinant proteins and stabilized using Seromatrix protein stabilizer. 

(1°) The IgG antibodies to COVID-19 present in serum or plasma samples are captured following an incubation time of 30 minutes. 

(2°) HRP labelled anti-human IgG antibodies bind the Fc region of the human IG antibodies present in the serum/plasma. 

(3°) The TMB substrate reacts with HRP and develops a blue color depending on the presence of the IgG antibodies in the samples.
