The SBC COVID-19 IgG ELISA Kit is an Enzyme-Linked Immunosorbent Assay (ELISA) intended for qualitative detection of IgG antibodies to SARS-CoV-2 in human serum.

High sensitivity and specificity

97.1% positive percent agreement (95% CI, 85.5%-99.5%)
Confirmed by testing 35 serum samples from patients that were confirmed positive for SARS-CoV-2 by US FDA authorized PCR 15- 40 days prior to serum collection.

100% negative percent agreement (95% CI, 95.8%-100%)
Confirmed by testing 87 serum samples collected in the US prior to December 2019.

Full-length spike protein coated microplates (S1 and S2)

SBC COVID-19 IgG ELISA Kit uses the full-length SARS-CoV-2 spike protein (S-protein) as the antigen for the detection of antibodies to SARS-CoV-2. Since the spike protein located at the outer shell of SARS-CoV-2, it’s the most potent candidate to induce adaptive immune response. By using full-length spike protein as antigen coated on the microplate, SBC COVID-19 IgG ELISA has become one of the most sensitive COVID-19 ELISA Kit in the world.
