Spike Protein (C-human IgG1-Fc, SARS-CoV-2)

1.Measured by its binding ability in a functional ELISA. Immobilized human ACE2 protein (His tag) at 2μg/mL (100μL/well) can bind SARS-CoV-2 (2019-nCoV) Spike Protein (S1 Subunit, Fc Tag) (40591-V02H), the EC50 of SARS-CoV-2 (2019-nCoV) Spike Protein (S1 Subunit, Fc Tag) is 10-50 ng/mL. 2.Recombinant SARS-CoV-2 (2019-nCoV) Spike S1 Protein, Fc Tag (Cat. No. 40591-V02H) captured on Protein A chip can bind Recombinant Human ACE2 Protein, His Tag (Cat. No. 10108-H08H) with an affinity constant of 1.50 nM as determined in an SPR assay (Biacore 8K) (Routinely tested) .
