| Product Name | Coronavirus Spike Glycoprotein, Recombinant, Bovine, aa326-540, His-Tag (S) |
|---|
| Description | Purity ~90% (SDS-PAGE). S1 attaches the virion to the cell membrane by binding to 9-O-acetylated sialic acid containing proteins, initiating the infection. S2 is a class I viral fusion protein. Under the current model, the protein has at least 3 conformational states: pre-fusion native state, pre-hairpin intermediate state, and post-fusion hairpin state. During viral and target cell membrane fusion, the coiled coil regions (heptad repeats) assume a trimer-of-hairpins structure, positioning the fusion peptide in close proximity to the C-terminal region of the ectodomain. The formation of this structure appears to drive apposition and subsequent fusion of viral and target cell membranes. Source: Recombinant protein corresponding to aa326-540 from bovine S, fused to His-Tag at N-terminal, expressed in Yeast. Molecular Weight: ~25.7kD AA |
