SARS-CoV-2 S1/RBD IgG ELISA from Tecan

Serological testing of IgG antibodies targeted against SARS-CoV-2 plays a vital role in finding out the incidence of the virus. Effective immune status tracking can be utilized for prescreening of individuals prior to vaccination, as well as for examining post-vaccination responses.1

Serological tests are not designed to find out the existence of the virus, but to identify an immune response by the body, thereby supplementing techniques that offer extra data on direct virus detection (for example, PCR testing).

Tecan’s SARS-CoV-2 S1/RBD IgG ELISA is a quantitative test that has the ability to detect IgG antibodies directed against the SARS-CoV-2-S1 spike protein’s receptor binding domain (RBD), which helps to find out the immune status.
