Functional Studies (Func), SDS-PAGE (SDS)
Characteristics Recombinant 2019-nCoV S1 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Gln14-Arg683) of 2019-ncov Spike S1 (Accession #YP_009724390.1) fused with a 6xHis tag and Avi at the C-terminus.
Purity > 95 % by SDS-PAGE
Endotoxin Level < 1.0 EU/μg of the protein by LAL method.
Biological Activity Comment Measured by its binding ability in a functional ELISA. Immobilized Recombinant 2019-nCoV Spike S1-His at 2μg/mL (100 μL/well) can bind Recombinant Human ACE2 with a linear range of 1.5-15 ng/mL.
Protein Name
Background Synonym: S1 protein, Spike glycoprotein Subunit1,S glycoprotein Subunit1,Spike protein S1,novel coronavirus s1 Protein
The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates thisinteraction.The S protein plays key parts in the induction of neutralizing-antibody and T-cellresponses, as well as protective immunity.
