Detection of SARS-CoV-2 Variant Proteins with Spike RBD Antibodies by Direct ELISA. Coating Antigen: SARS-CoV-2 full length spike proteins, including WT, UK variant (B.1.1.7), SA variant (B.1.135) and Brazil (P.1). Dilution: 10-3000 ng/mL. Incubate at 4 °C overnight. Detection Antibodies: SARS-CoV-2 Spike RBD Antibody, orb1239994, 2 µg/mL, incubate at RT for 1 hr. Secondary Antibodies: Goat anti-rabbit HRP at 1:20000, incubate at RT for 1 hr. Immunogen region of antibody (orb1239994) includes site 501N that was mutated in all three variants. orb1239994 has low binding affinity for all three variants as compared to WT.

ELISA Validation with SARS

Immunohistochemistry Validation of SARS-CoV-2 (COVID-19) Spike RBD in COVID-19 Patient Lung. Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using anti-SARS-CoV-2 (COVID-19) Spike RBD antibody (orb1239994, 0.5 µg/mL). Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT, antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4 °C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin. Strong signal of SARS-COV-2 Spike RBD protein was observed in macrophage of COVID-19 patient lung, but not in non-COVID-19 patient lung.
