Indirect ELISA analysis was performed by coating plate with 50 μL of recombinant SARS-CoV-2 (COVID-19) spike S1 subunit protein, and SARS-CoV spike S1 subunit protein at concentrations ranging from 0.0625 μg/mL to 4 μg/mL. The coated protein is detected with SARS-CoV-2 (COVID-19) Spike S1 antibody [HL134] (GTX635671) at 1 μg/mL. Rabbit IgG antibody (HRP) (GTX213110-01) was diluted at 1:10000 and used to detect the primary antibody.

Non-transfected (–) and transfected (+) 293T whole cell extracts (30 μg) were separated by 5% SDS-PAGE, and the membrane was blotted with SARS-CoV-2 (COVID-19) Spike S1 antibody [HL134] (GTX635671) diluted at 1:5000. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody.

Indirect ELISA analysis performed by coating plate with recombinant SARS-CoV-2 (COVID-19) spike S1 subunit protein (50 ng). Coated protein probed with SARS-CoV-2 (COVID-19) Spike S1 antibody [HL134] (GTX635671) (2.4*10⁻⁶ ~ 20 nM). Rabbit IgG antibody (HRP) (GTX213110-01) (1:10000) detected bound primary antibody.
