Product Specifications

Abbreviation

Spike

Host

HEK 293

Tag

C-His

Endotoxin

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

Purity

Bioactivity

Measured by its binding ability in a functional ELISA. Immobilized Human ACE2 (mFc tag) (Cat: 10108-H05H) at 2 μg/mL (100 μL/well) can bind SARS-CoV-2 (2019-nCoV) Spike RBD (E484Q) -His (Cat:40592-V08H81), the EC50 of SARS-CoV-2 (2019-nCoV) Spike RBD (E484Q) -His (Cat:40592-V08H81) is 5.0-25.0 ng/mL.

Function

Arg319-Phe541 (E484Q)

Molecular Weight

The recombinant SARS-CoV-2 (2019-nCoV) Spike S1 (Arg319-Phe541 (E484Q) ) -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 35.1 kDa band in SDS-PAGE under reducing conditions.
