• Purity: >95% as determined by SDS-PAGE
• Synonyms: FGF23; Recombinant Human FGF23; FGF-23; Phosphatonin; Tumor-derived hypophosphatemia-inducing factor; HYPF; Recombinant Human Fibroblast Growth Factor 23 (FGF23); FGF23 active protein

• Host: E Coli
• Purity/Purification: >95% as determined by SDS-PAGE
• Form/Format: Lyophilized from 0.2 um filtered PBS solution, pH 7.4.
• Sequence Length: 251

• Bioactivity: The ED(50) was determined by the dose-dependent proliferation of mouse 3T3 cells expressing FGF receptors, and was found to be < 0.3 ug/mL, corresponding to a specific activity of 3.0 x 10^4 units/mg.
• Endotoxin Level: <1.0 EU/ug of recombinant protein as determined by the LAL method.
• Reconstitution: A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
• Preparation and Storage: The lyophilized protein is stable for at least one year from date of receipt at-70 degree C. Upon reconstitution, this cytokine can be stored in working aliquots at 2-8 degree C for one month, or at-20 degree C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Related Product Information for FGF23 active protein

FGF-23 is a protein of 30 kDa that is proteolytically processed to generate smaller N-terminal (18 kDa) and C-terminal (12 kDa) fragments. The N-terminal fragment of FGF-23 contains the FGF receptor (FGFR)-binding domain. In vivo studies using synthetic peptides have indicated that neither of the processed N-terminal or C-terminal fragments of FGF-23 can influence serum phosphate levels. FGF-23 can decrease the activity of NaPi-2a and NaPi-2c cotransporters to reduce renal phosphate reabsorption and thereby can increase urinary phosphate excretion. Similarly, FGF-23 can suppress the expression of 1-alpha-hydroxylase to reduce the production of the active vitamin D metabolite 1, 25(OH)2D. Moreover, FGF-23 can also induce 24-hydroxylase, which degrades 1, 25(OH)2D

NCBI Description

This gene encodes a member of the fibroblast growth factor family of proteins, which possess broad mitogenic and cell survival activities and are involved in a variety of biological processes. The product of this gene regulates phosphate homeostasis and transport in the kidney. The full-length, functional protein may be deactivated via cleavage into N-terminal and C-terminal chains. Mutation of this cleavage site causes autosomal dominant hypophosphatemic rickets (ADHR). Mutations in this gene are also associated with hyperphosphatemic familial tumoral calcinosis (HFTC).

Uniprot Description

FGF23: Regulator of phosphate homeostasis. Inhibits renal tubular phosphate transport by reducing SLC34A1 levels. Upregulates EGR1 expression in the presence of KL. Acts directly on the parathyroid to decrease PTH secretion. Regulator of vitamin-D metabolism. Negatively regulates osteoblast differentiation and matrix mineralization. Defects in FGF23 are the cause of autosomal dominant hypophosphataemic rickets (ADHR). ADHR is characterized by low serum phosphorus concentrations, rickets, osteomalacia, leg deformities, short stature, bone pain and dental abscesses. Defects in FGF23 are a cause of hyperphosphatemic familial tumoral calcinosis (HFTC). HFTC is a severe autosomal recessive metabolic disorder that manifests with hyperphosphatemia and massive calcium deposits in the skin and subcutaneous tissues. Belongs to the heparin-binding growth factors family.
