SARS-CoV-2 ELISA kits remain essential tools for monitoring immune responses, validating vaccines, and supporting ongoing coronavirus research. Our portfolio includes ELISAs targeting the Nucleocapsid (N) protein, the Spike protein, and SARS-CoV-2–specific IgG antibodies—each serving distinct and valuable purposes. N-protein ELISAs are widely used for detecting early seroconversion and evaluating exposure, as the N protein is highly immunogenic and abundantly expressed during infection. Spike-protein ELISAs, particularly those focused on the RBD region, are central for assessing vaccine-induced immunity and for measuring antibody responses against updated viral variants. IgG-based ELISA kits provide longer-term immune profiling, as IgG is the most durable antibody isotype following infection or vaccination; while IgM rises early and declines quickly, IgG persists and therefore allows researchers to track immune memory, compare antibody titers over time, or characterize post-vaccination responses. Each kit we offer is optimized for sensitivity, reproducibility, and compatibility with serum or plasma samples.
