Indirect ELISA analysis performed by coating plate with recombinant Spike RBD Protein(s) derived from different strains of SARS-CoV-2 virus (ie., Wild type; B.1.1.529 Omicron variant) (159.36-2.49 nM). Coated protein was probed with SARS-CoV-2 (COVID-19) Spike RBD antibody (GTX135709) (1 μg/mL). Goat anti-rabbit IgG antibody (HRP) (GTX213110-01) (1:10000) was used to detect bound primary antibody.

SARS-CoV-2 (COVID-19) Spike RBD Protein, B.1.1.529 / Omicron variant, His tag protein (GTX136716-pro) were separated by 12% SDS-PAGE, and the membrane was blotted with the SARS-CoV-2 (COVID-19) Spike RBD antibody [HL257] (GTX635692) diluted at 1:5000.

Indirect ELISA analysis performed by coating plate with recombinant SARS-CoV-2 (COVID-19) Spike RBD Protein, B.1.1.529 / Omicron variant, His tag (GTX136716-pro) (159.36-2.49 nM).
