SARS-CoV-2 ELISA kits are assays designed to measure levels of SARS-CoV-2-related antigens in biological samples, such as plasma, serum, culture extracts, and cell lysates. The target antigens can include proteins found on the SARS-CoV-2 viral particles, such as S (spike), E (envelope), M (membrane), and N (nucleocapsid). Immunoglobulins raised in response to an infection, such as IgG or IgM, may also serve as targets for some assay kits. SARS-CoV-2 is the pathogen that causes COVID-19, an infectious respiratory disease. SARS-CoV-2 ELISA kits utilize microtiter plates coated with specific antibodies and conjugated detection enzymes. The assay will produce a detectable signal proportional to the amount of SARS-CoV-2 antigens found in the sample.
