Notes: Cayman’s Anti-SARS-CoV-2 Spike Glycoprotein RBD IgG ELISA Kit is an enzyme-linked immunosorbent assay that can be used for the qualitative assessment of the presence of antibodies against the SARS-CoV-2 spike glycoprotein RBD in human plasma and serum. In general, while PCR positivity indicates the presence of viral antigens, this serological assay indicates the presence of IgG antibodies against the SARS-CoV-2 spike glycoprotein RBD, which occurs in the weeks following SARS-CoV-2 infection. The IgG response measured in this kit does not differentiate neutralizing antibodies, which specifically interrupt the interaction between the spike glycoprotein RBD and the ACE2 receptor on the host cell, from non-neutralizing antibodies that bind to the RBD. A positive control is included in this kit to provide a cut-off for seropositivity.
