Spike glycoprotein (S), partial, Bat coronavirus HKU3, recombinant

Organism: Bat coronavirus HKU3 (BtCoV) (SARS-like coronavirus HKU3). Source: E.coli. Expression Region: 310-514aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: RVSPTQEVIR FPNITNRCPF DKVFNATRFP NVYAWERTKI SDCVADYTVL YNSTSFSTFK CYGVSPSKLI DLCFTSVYAD TFLIRSSEVR QVAPGETGVI ADYNYKLPDD FTGCVIAWNT AKHDTGNYYY RSHRKTKLKP FERDLSSDDG NGVYTLSTYD FNPNVPVAYQ ATRVVVLSFE LLNAPATVCG PKLSTELVKN QCVNF. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Lyophilized powder. Buffer: Lyophilized from 10 mM Tris-HCl, 1 mM EDTA, 6% Trehalose, pH 8.0. 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
