SARS-COV-2 S1 Protein (N501Y, K417N, E484K, HEK293, His)

The SARS-Cov-2 S glycoprotein is a SARS-Cov-2 S glycoprotein. The amino acid sequence 1261-1267a.a of the SARS-Cov-2 S glycoprotein is transmembrane. The SARS-Cov-2 S glycoprotein is a highly glycosylated trimer, each of which consists of 1260 amino acids (residues 14-1273), divided into four structural domains: the n-terminal domain (NTD), the c-terminal domain (CTD, also known as the receptor-binding domain, RBD), and two subdomains (SD1 and SD2). SARS-COV-2 S1 Protein (N501Y, K417N, E484K, HEK293, His) is the recombinant Virus-derived SARS-COV-2 S1 protein, expressed by HEK293 , with C-His labeled tag. The total length of SARS-COV-2 S1 Protein (N501Y, K417N, E484K, HEK293, His) is 670 a.a., with molecular weight of 90-130 kDa.

SARS-Cov-2 is a enveloped positive-sense single-stranded RNA virus that causes COVID-19.
SARS-CoV-2 possesses four structural proteins, namely the envelope protein (E), spike or surface glycoprotein (S), membrane protein (M), and nucleocapsid protein (N).
The SARS-Cov-2 S glycoprotein is located on the exterior of the viral particle, giving the coronavirus its crown-like appearance.
The SARS-Cov-2 S glycoprotein can mediate the attachment and entry of viral particles into host cells and is an important target for vaccine development, antibody therapy, and antigen-based diagnostic esting^{[1][2][3][4][5]}.
