Anti-SARS-CoV-2 Nucleocapsid (NP) Human IgA ELISA Kit

• Catalog Number: orb2975620
• Category: Assays and Kits
• Description: PRINCIPLE OF THE ASSAY This assay employs the quantitative indirect enzyme immunoassay technique. Recombinant SARS-CoV-2 Nucleocapsid (NP) has been pre-coated onto a microplate. Standards or samples are pipetted into the wells and any Anti-SARS-CoV-2 Nucleocapsid (NP) Human IgA present is bound by the immobilized protein. After washing away any unbound substances, a biotin-labeled Mouse Anti-Human IgA antibody is added to the wells. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of Anti-SARS-CoV-2 Nucleocapsid (NP) Human IgA bound in the initial step. The color development is stopped and the intensity of the color is measured.
