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.
The protein has a calculated MW of 34.4 kDa.
The protein migrates as 50-63 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Source：SARS-CoV-2 Spike NTD Protein, His Tag (BA.4 & BA.5/Omicron) (SPD-C5246) is expressed from human 293 cells (HEK293). It contains AA Ser 13 - Leu 303 (Accession # QHD43416.1 (T19I, LPP24-26del, A27S, HV69-70del, G142D, V213G)). The spike mutations are identified on the SARS-CoV-2 Omicron variant (Pango lineage: BA.4 and BA.5).
