1. Measured by its binding ability in a functional ELISA. Immobilized human ACE2 protein (Fc tag)(Cat: 10108-H05H) at 2 μg/mL (100 μL/well) can bind SARS-CoV-2/2019-nCoV Spike Protein (S1 Subunit, His tag) (40591-V08H), the EC50 of SARS-CoV-2/2019-nCoV Spike Protein (S1 Subunit, His tag) (Cat: 40591-V08H) is 200-600 ng/mL.
A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) spike protein S1 Subunit (YP_009724390.1) (Val16-Arg685) was expressed with a polyhistidine tag at the C-terminus.
Predicted N Terminal
The recombinant SARS-CoV-2 (2019-nCoV) Spike Protein (S1 Subunit, His Tag) consists of 681 amino acids and predicts a molecular mass of 76.5 kDa.
Lyophilized from sterile PBS, pH 7.4.
