Fibroblast growth factor 23 (Fgf23), rat, recombinant

Organism: Rattus norvegicus (Rat). Source: Yeast. Expression Region: 25-251aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: YSDTSPLLGS NWGSLTHLYT ATARNSYHLQ IHRDGHVDGT PHQTIYSALM ITSEDAGSVV IIGAMTRRFL CMDLRGNIFG SYHFSPENCR FRQWTLENGY DVYLSPKHHY LVSLGRSKRI FQPGTNPPPF SQFLARRNEV PLLHFYTARP RRHTRSAEDP PERDPLNVLK PRPRATPIPV SCSRELPSAE EGGPAASDPL GVLRRGRGDA RRGAGGTDRC RPFPRFV. 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: Regulator of phosphate homeostasis . Inhibits renal tubular phosphate transport by reducing SLC34A1 levels . Regulator of vitamin-D metabolism . Negatively regulates osteoblasts differentiation and matrix mineralization . Acts directly on the parathyroid to decrease PTH secretion. Upregulates EGR1 expression in the presence of KL.
