Characteristics :

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 79.4 kDa. The protein migrates as 95-110 kDa under reducing (R) condition (SDS-PAGE) due to Glycosylation.

 

Endotoxin Level : Less than 1.0 EU per μg by the LAL method.

 

Buffer : PBS, pH7.4

 

Description :

It’s been reported that Coronavirus can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
