Spike Protein (C-His, SARS-CoV-2)

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

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 RBD (Y453F) -His (40592-V08H80), the EC50 of SARS-CoV-2 (2019-nCoV) Spike RBD (Y453F) -His (40592-V08H80) is 5-20 ng/mL.

Function

Arg319-Phe541 (Y453F)

Molecular Weight

The recombinant SARS-CoV-2 (2019-nCoV) Spike RBD (Y453F) -His Recombinant Protein consists of 234 amino acids and predicts a molecular mass of 26.5 kDa. As a result of glycosylation, it migrates as an approximately 35.6 kDa band in SDS-PAGE under reducing conditions.
