Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg\/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃\/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.\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℃. The shelf life of lyophilized form is 12 months at -20℃\/-80℃.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eNotes\u003c\/b\u003e: Repeated freezing and thawing is not recommended.

Under the current model, the protein has at least three 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. ; [Spike protein S2']:  Acts as a viral fusion peptide which is unmasked following S2 cleavage occurring upon virus endocytosis.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: \u003c\/p\u003e\u003cp\u003e\u003cb\u003eFunction\u003c\/b\u003e: \u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47785555066980,"sku":"A3EXG6","price":1257.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_3865cc9b-0f04-4381-be72-286461a707d4.jpg?v=1769550262","url":"https:\/\/www.genebiosystems.com\/en-us\/products\/recombinant-bat-coronavirus-hku9-spike-glycoprotein-s-partial","provider":"GeneBio ","version":"1.0","type":"link"}
