AdipoGen Life Sciences<\/strong> has developed a sensitive<\/strong> and specific SARS-CoV-2 (Spike RBD) IgG Serological ELISA Kit<\/strong> (Prod. No. AG-45B-0020<\/a>) that can be used for the qualitative measurement of human Immunoglobulin G (IgG) against SARS-CoV-2 Spike (Receptor Binding Domain) protein in serum and plasma samples.<\/p>\n\n\n\n

During an infection, IgM antibodies appear first, followed by IgA on mucosal surfaces or IgG in the serum. The spike (S) proteins (mainly the RBD domain) and the nucleocapsid (N) proteins are the main immunogens of coronaviruses leading to an antibody answer. This assay is an indirect ELISA assay (based on a coated Spike (RBD) protein).<\/p>\n\n\n\n

Included in this assay and unique<\/strong> in the market for SARS-CoV-2 IgG assays, is a second plate (antigen non-coated Background Plate or False Positive Control Plate<\/strong>) to determine the sample-specific background and to measure the amount of IgG antibodies non-specifically bound to the well. To measure the presence of anti-SARS-CoV-2 human IgG antibodies in serum or plasma, net sample optical densities (Net OD) are calculated by subtracting each sample Background Plate OD from the Spike (SARS-CoV-2) antigen plate (Spike Plate) OD.<\/p>\n\n\n\n

Note:<\/p>\n\n\n\n

\u2022 In the first week of the onset of the infection with the novel coronavirus (SARS-CoV-2) patients’ results may be negative for IgG.<\/p>\n\n\n\n

\u2022 Patients with low immunity or other diseases that affect immune function, failure of important systemic organs, and use of drugs that suppress immune function can also lead to negative results of new coronavirus IgG.<\/p>\n\n\n\n

\u2022 Previous infection of SARS or other coronavirus strains may cause a light IgG positive in view of similarities in the nucleocapsid protein, but not in the Spike RBD protein. This means that nucleocapsid-based SARS-CoV-2 IgG assays have a higher chance of cross-reactivities with other coronavirus IgG antibodies than Spike RBD-based SARS-CoV-2 IgG assays<\/strong>, such as this newly developed assay from AdipoGen Life Sciences.<\/p>\n\n\n\n
