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.

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 76.9 kDa. The protein migrates as 110-130 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

SARS-CoV-2 S1 protein (N501Y), His Tag (S1N-C52Hg) is expressed from human 293 cells (HEK293). It contains AA Val 16 - Arg 685 (Accession # QHD43416.1 (N501Y)). N501Y mutaion was identified in both the SARS-CoV-2 variant (known as 20 B/501 Y.V1, VOC 202012/01, or B0.1.1.7 lineage) which emerged in the United Kindom and SARS-CoV-2 variant (known as 20 C/501 Y.V2 or B0.1.351 lineage) which emerged in South Africa.
