Spike glycoprotein (S), partial, human coronavirus OC43, recombinant

Organism: Human coronavirus OC43 (HCoV-OC43). Source: E.coli. Expression Region: 15-344aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: VIGDLKCTSD NINDKDTGPP PISTDTVDVT NGLGTYYVLD RVYLNTTLFL NGYYPTSGST YRNMALKGSV LLSRLWFKPP FLSDFINGIF AKVKNTKVIK DRVMYSEFPA ITIGSTFVNT SYSVVVQPRT INSTQDGDNK LQGLLEVSVC QYNMCEYPQT ICHPNLGNHR KELWHLDTGV VSCLYKRNFT YDVNADYLYF HFYQEGGTFY AYFTDTGVVT KFLFNVYLGM ALSHYYVMPL TCNSKLTLEY WVTPLTSRQY LLAFNQDGII FNAEDCMSDF MSEIKCKTQS IAPPTGVYEL NGYTVQPIAD VYRRKPNLPN CNIEAWLNDK. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Lyophilized powder. Buffer: Lyophilized from Tris/PBS-based buffer, 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
