Binding activity of SARS-CoV-2-S antibodies

Binding Activity of SARS-CoV-2-S Antibody measured by its binding ability in a functional ELISA. Wells were coated with Recombinant Human Novel Coronavirus Spike glycoprotein(S) (AS20 4389) at 2 μg/ml. EC₅₀ of SARS-CoV-2-S antibodies is 36.79 - 48.87 ng/ml.

Additional information

Recombinant anti-SARS-CoV-2 spike Mouse ScFv is expressed in 293 cells (HEK293) with a human IgG1 Fc tag on C-terminal. Therefore, anti-human IgG1 Fcγ (gamma chain), secondary antibody has to be used: AS20 4390
