Spike glycoprotein (S), partial, Severe acute respiratory syndrome coronavirus, recombinant

Organism: Severe acute respiratory syndrome coronavirus (SARS-CoV). Source: Mammalian cell. Expression Region: 306-527aa. Protein Length: Partial. Tag Info: C-terminal 6xHis-tagged. Target Protein Sequence: RVVPSGDVVR FPNITNLCPF GEVFNATKFP SVYAWERKKI SNCVADYSVL YNSTFFSTFK CYGVSATKLN DLCFSNVYAD SFVVKGDDVR QIAPGQTGVI ADYNYKLPDD FMGCVLAWNT RNIDATSTGN YNYKYRYLRH GKLRPFERDI SNVPFSPDGK PCTPPALNCY WPLNDYGFYT TTGIGYQPYR VVVLSFELLN APATVCGPKL STDLIKNQCV NF. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Less than 1.0 EU/ug as determined by LAL method. Biological Activity: n/a. Form: Lyophilized powder. Buffer: Lyophilized from a 0.2 µm sterile fiiltered 20mM Tris-HCl,400mM NaCl,6% Trehalose,pH 7.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. 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 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. 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 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: n/a. Reference: n/a. Function: nan
