Spike protein is an envelope-anchored protein that mediates the recognition and binding of coronaviruses (SARS-CoV-2/COVID-19) to host cells. Spike protein can be further cleaved by the host protease into two subunits called S1 and S2, wherein the S1 subunit contains a receptor binding domain (RBD) crucial for the specific recognition and interaction with the host cell receptor, ACE2. This is the first and the most essential step for the virus infection. Immunoglobulin A (IgA) plays a crucial role in the immune function of mucous membranes. In the blood, IgA interacts with Fc receptor to initiate inflammatory responses.

SARS-CoV-2 S1 protein IgG ELISA Kit is a highly sensitive and specific immunoassay for the precision detection and qualitative measurement of IgA class antibodies against the spike S1 protein of SARS-CoV-2 virus in human blood samples in vitro.
