Product Specifications

Abbreviation

Spike

Host

HEK 293

Tag

C-His

Endotoxin

< 1.0 EU per μg protein as determined by the LAL method.

Purity

> 95 % as determined by SDS-PAGE

Bioactivity

Immobilized human ACE2 protein (mFc tag) (Cat:10108-H05H) at 2 μg/mL (100 μL/well) can bind SARS-CoV-2 Spike RBD (N501S) Protein (His Tag) (Cat:40592-V08H119), the EC50 is 10-120 ng/mL.

Function

Arg319-Phe541

Molecular Weight

The recombinant SARS-CoV-2 Spike RBD consists of 234 amino acids and predicts a molecular mass of 26.52 kDa. As a result of glycosylation, it migrates as an approximately 37.75 kDa band in SDS-PAGE under reducing conditions.
