COVID-19 Human IgM PharmaGenie ELISA Kit (NP/S1 RBD) (SBRS1733)

Manufactured by Assay Genie, this indirect-format kit detects human IgM antibodies directed against the SARS-CoV-2 nucleocapsid protein (NP) and the S1 receptor-binding domain (RBD). IgM serology is the leading indicator of recent or acute infection, making this assay valuable for early-phase screening, contact-tracing studies, and seroprevalence surveillance programmes. Researchers also apply it to vaccine immunogenicity trials and to characterise convalescent donor sera. Reagents should be stored according to the kit insert and protected from repeated freeze-thaw cycles to preserve antibody-binding performance across the microplate.
