HEK 293
Tag
C-human IgG1-Fc
Endotoxin
< 1.0 EU per μg protein as determined by the LAL method.
Purity
> 90 % as determined by SDS-PAGE
Bioactivity
Immobilized human ACE2 protein (His tag) (10108-H08H) at 2 μg/mL (100 μL/well) can bind SARS-CoV-2 Spike RBD (R346K, E484K, N501Y) Protein (Fc Tag) (Cat: 40592-V02H6), the EC50 is 0.6-6.8 ng/mL.
Function
Arg319-Phe541
Molecular Weight
The recombinant SARS-CoV-2 Spike RBD consists of 461 amino acids and predicts a molecular mass of 51.84 kDa. As a result of glycosylation, it migrates as an approximately 56.07 kDa band in SDS-PAGE under reducing conditions.
