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.
特徴
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag).
The protein has a calculated MW of 28.3 kDa.
The protein migrates as 30-40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Source：Biotinylated SARS-CoV-2 Spike RBD Protein (L452R), His,Avitag (SPD-C82E3) is expressed from human 293 cells (HEK293). It contains AA Arg 319 - Lys 537 (Accession # QHD43416.1 (L452R)). The L452R mutation was identified in the SARS-CoV-2 Epsilon variant (Pango lineage: B.1.427/B.1.429; other names: 20C/S:452R, or CAL.20C).
