Bioactivity

Immobilized human ACE2 protein (mFc tag) (Cat:10108-H05H) at 2 μg/mL (100 μL/well) can bind SARS-CoV-2 Spike S1 (L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, D614G, H655Y) Protein (His Tag) (Cat:40591-V08H14), the EC50 of SARS-CoV-2 Spike S1 (L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, D614G, H655Y) Protein (His Tag) (Cat:40591-V08H14) is 15-90 ng/mL.

Function

Met1-Arg685 (L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, D614G, H655Y)

Molecular Weight

The recombinant SARS-CoV-2 (2019-nCoV) Spike S1 consists of 681 amino acids and predicts a molecular mass of 76.5 kDa. As a result of glycosylation, it migrates as an approximately 113.9 kDa band in SDS-PAGE under reducing conditions.
