Development of an Antigen Detection Kit Capable of Discriminating the Omicron Mutants of SARS-CoV-2.

In this study, monoclonal antibodies with high specificity to the N protein of the Omicron mutant strain were obtained by monoclonal antibody screening technology. Colloidal gold immunochromatography technology was used to prepare an antigen detection kit with high sensitivity to detect and identify the mutant Omicron strain.
