Fructose-1,6-bisphosphatase 1 (FBP1), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 2-338aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 10xHis-SUMO-tagged and C-terminal Myc-tagged. Target Protein Sequence: ADQAPFDTDV NTLTRFVMEE GRKARGTGEL TQLLNSLCTA VKAISSAVRK AGIAHLYGIA GSTNVTGDQV KKLDVLSNDL VMNMLKSSFA TCVLVSEEDK HAIIVEPEKR GKYVVCFDPL DGSSNIDCLV SVGTIFGIYR KKSTDEPSEK DALQPGRNLV AAGYALYGSA TMLVLAMDCG VNCFMLDPAI GEFILVDKDV KIKKKGKIYS LNEGYARDFD PAVTEYIQRK KFPPDNSAPY GARYVGSMVA DVHRTLVYGG IFLYPANKKS PNGKLRLLYE CNPMAYVMEK AGGMATTGKE AVLDVIPTDI HQRAPVILGS PDDVLEFLKV YEKHSAQ. 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: Catalyzes the hydrolysis of fructose 1,6-bisphosphate to fructose 6-phosphate in the presence of divalent cations, acting as a rate-limiting enzyme in gluconeogenesis. Plays a role in regulating glucose sensing and insulin secretion of pancreatic beta-cells. Appears to modulate glycerol gluconeogenesis in liver. Important regulator of appetite and adiposity, increased expression of the protein in liver after nutrient excess increases circulating satiety hormones and reduces appetite-stimulating neuropeptides and thus seems to provide a feedback mechanism to limit weight gain.
