The newly identified coronavirus, SARS-CoV-2 (2019-nCoV), led to pneumonia (COVID-19). SARS-CoV-2 belongs to the genus of betacoronaviruses, which also includes the SARS CoV (2003) and the MERS CoV (2012). Like all other coronaviruses, the SARS-CoV-2 genome (2019-nCoV) codes for the spike protein, envelope protein, membrane protein and nucleocapsid protein.

Several methods are available to detect the presence of CoV-2-SARS in samples. The 3 main ones are RT-qPCR, which consists of detecting the presence of viral RNA using probes and primers specific to certain viral genes, immunochromatography (rapid test), which consists of detecting the presence of antibodies directed against SARS-CoV-2 antigens, and finally, the ELISA technique.

The ELISA technique, unlike the other two methods, is currently more intended for research than for the diagnosis of COVID-19. This technique makes it possible to measure either SARS-CoV-2 antigens or antibodies to these antigens, depending on the chosen strategy. We propose these 2 types of ELISA kits in our catalogue.
