SARS-CoV-2 Spike RBD Protein, His Tag (B.1.1.529/Omicron) (Trehalose free) (MALS verified)
SARS-CoV-2 Spike RBD, His Tag (B.1.1.529/Omicron) (SPD-C522f) is expressed from human 293 cells (HEK293) .
Product Specifications
Background
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.
Specifications
This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 26.8 kDa. The protein migrates as 33-38 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
