Recombinant Bovine coronavirus

host_species:E.coli

purification:Greater than 85% as determined by SDS-PAGE.

other_names:E2 Peplomer protein

accession_no:P15777

calculated_mw:27.2 kDa

tag info:N-terminal 10xHis-tagged

Immunogen Description:Expression Region:326-540aa
Sequence Info:Partial

formulation:Tris-based buffer50% glycerol

storage:The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃,-80℃. The shelf life of lyophilized form is 12 months at -20℃,-80℃.
Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

background: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, 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
