Long-chain fatty acid transport protein (fadL), Escherichia coli O157:H7, recombinant

Organism: Escherichia coli O157:H7. Source: E.coli. Expression Region: 26-446aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: AGFQLNEFSS SGLGRAYSGE GAIADDAGNV SRNPALITMF DRPTFSAGAV YIDPDVNISG TSPSGRSLKA DNIAPTAWVP NMHFVAPIND QFGWGASITS NYGLATEFND TYAGGSVGGT TDLETMNLNL SGAYRLNNAW SFGLGFNAVY ARAKIERFAG DLGQLVAGQI MQSPAGKTPQ GQALAATANG IDSNTKIAHL NGNQWGFGWN AGILYELDKN NRYALTYRSE VKIDFKGNYS SDLNRVFNNY GLPIPTATGG ATQSGYLTLN LPEMWEVSGY NRVDPQWAIH YSLAYTSWSQ FQQLKATSTS GDTLFQKHEG FKDAYRIALG TTYYYDDNWT FRTGIAFDDS PVPAQNRSIS IPDQDRFWLS AGTTYAFNKD ASVDVGVSYM HGQSVKINEG PYQFESEGKA WLFGTNFNYA F. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is 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: Involved in translocation of long-chain fatty acids across the outer membrane. FadL may form a specific channel.
