SARS-CoV-2 S protein RBD trimer, His Tag (SPD-C52M5) is expressed from human 293 cells (HEK293).
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 67.1 kDa. The protein migrates as 66-80 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Supplied as 0.2 μm filtered solution in PBS, pH7.4.

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.
