COVID-19 ELISA

Antibody screening has important public health uses in determining immunity to and prevalence of COVID-19, as well as identifying who has been infected and evaluating potential blood based therapeutics. Detect IgG, IgM, and IgA antibodies to COVID-19 N and S1 RBD proteins in serum, plasma, and dried blood samples using the COVID-19 Indirect ELISA kits. Additionally, use the sandwich ELISAs for detecting N- and S-Proteins.
