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\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: \"Deduced sequence of the bovine coronavirus spike protein and identification of the internal proteolytic cleavage site.\"\nAbraham S., Kienzle T.E., Lapps W.E., Brian D.A.\nVirology 176:296-301(1990)\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e: Greater than 85% as determined by SDS-PAGE.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStorage\u003c\/b\u003e: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. \nGenerally, the shelf life of liquid form is 6 months at -20℃\/-80℃.
