  • Background: It's been reported that SARS-CoV-2 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.
  • Exp Region: Met 1 - Gln 1200
  • Characteristics: This protein carries a polyhistidine tag at the C-terminus, followed by a twin strep tag. The protein has a calculated MW of 141.2 kDa. The protein migrates as 170-190 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
