>96%, as determined by SDS-PAGE and HPLC

Human Basic FGF was lyophilized from a 0.2 um filtered solution in 1M NaCl,20mM PB pH 7.0.

The lyophilized protein is stable for at least 2 years from date of receipt at -20 degree C. Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree - 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.

Domain: HBGF/IL1. Host Note: Optimized DNA sequence encoding Human basic Fibroblast Growth Factor mature chain was expressed in Escherichia Coli.

Endotoxin: Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/ug (1EU/ug). 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. Molecular Weight Note: Native human FGF basic is generated by the proteolytic removal of the signal peptide. and propeptide,the molecule has a calulated mass of 17 kDa. Recombinant bFGF is a disulfide-linked homodimeric protein consisting of 155 amino acid residue subunits, and migrates as an approximately 17 kDa protein under non-reducing and reducing conditions in SDS-PAGE.

Cytokines

basic Fibroblast Growth Factor is found in almost all tissues of mesodermal and neuroectodermal origin and also in tumors derived from these tissues. Endothelial cells produce large amounts of this factor. Some bFGF is associated with the extracellular matrix of the subendothelial cells. Many cells express bFGF only transiently and store it in a biologically inactive form. The mechanism by which the factor is released by the cells is not known. It is released after tissue injuries and during inflammatory processes. FGF receptors are encoded by a gene family consisting of at least four receptor tyrosine kinases that transduce signals important in a variety of developmental and physiological processes related to cell growth and differentiation. bFGF stimulates the growth of fibroblasts, myoblasts, osteoblasts, neuronal cells, endothelial cells, keratinocytes, chondrocytes, and many other cell types.

Function: Plays an important role in the regulation of cell survival, cell division, angiogenesis, cell differentiation and cell migration. Functions as potent mitogen in vitro. Ref.11 Ref.20. Subunit structure: Monomer. Homodimer. Interacts with FGFR1, FGFR2, FGFR3 and FGFR4. Affinity between fibroblast growth factors (FGFs) and their receptors is increased by heparan sulfate glycosaminoglycans that function as coreceptors. Interacts with CSPG4, FGFBP1 and TEC. Found in a complex with FGFBP1, FGF1 and FGF2. Ref.19 Ref.20 Ref.21 Ref.22 Ref.23 Ref.24 Ref.25. Subcellular location: Secreted. Nucleus. Note: Exported from cells by an endoplasmic reticulum (ER)/Golgi-independent mechanism. Unconventional secretion of FGF2 occurs by direct translocation across the plasma membrane. Binding of exogenous FGF2 to FGFR facilitates endocytosis followed by translocation of FGF2 across endosomal membrane into the cytosol. Nuclear import from the cytosol requires the classical nuclear import machinery, involving proteins KPNA1 and KPNB1, as well as CEP57. Ref.25 Ref.28. Tissue specificity: Expressed in granulosa and cumulus cells. Expressed in hepatocellular carcinoma cells, but not in non-cancerous liver tissue. Ref.11 Ref.18. Post-translational modification: Phosphorylation at Tyr-215 regulates FGF2 unconventional secretion.Several N-termini starting at positions 94, 125, 126, 132, 143 and 162 have been identified by direct sequencing. Miscellaneous: This protein binds heparin more strongly than does aFGF. Sequence similarities: Belongs to the heparin-binding growth factors family. Biophysicochemical propertiespH dependence:Retains almost half of its activity after treatment at pH 2.0 for 3 hours at 20 degrees Celsius. Ref.11Temperature dependence:Inactivated after 3 minutes at 60 degrees Celsius or 1 minute at 80 degrees Celsius. Sequence caution: The sequence AAA52448.1 differs from that shown.
