Recombinant Human FGF2 (Fibroblast Growth Factor 2)

SKU: BP07013-10ug
$50.00Price

 

Size
  • Accession Number

    P09038
  • Expression

    E.coli
  • Formulation

    The protein was lyophilized from a concentrated (0.5 mg/ml) solution of PBS.

  • Endotoxin

    Less than 0.05 ng/µg (0.5 EU/µg) of hFGF-2.

  • Purity

    >98.0% as determined by Gel filtration at non denaturing conditions using 25 nM Tris-HCl + 150 nM NaCl, pH 8., and Analysis by reducing and non-reducing SDS-PAGE gel

  • Activity

    The activity was determined by the dose-dependant proliferation of mouse BALB/c 3T3 cells.

  • Reconstitution and Solubility

    It is recommended to reconstitute the lyophilized hFGF-2 in water, not less than 100µg/ml, which can then be further diluted to other aqueous solutions, preferably in a presence of a carrier protein such as BSA or similar. Dissolve gently; never vortex.

  • Stability

    Lyophilized hFGF-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution and filter sterilization hFGF-2 should be aliquoted and frozen. For long term storage and more diluted solutions it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.

  • Amino Acid Sequence

    The sequence of the first six N-terminal amino acids was determined and was found to be MPALPE

  • Dimers and Aggregates

    Less than 10% dimers as determined by gel filtration chromatography and no aggregates.

  • Quantitation

    Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.88 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the DNAman computer analysis program of protein sequences.

  • Background

    FGF-basic is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Three alternatively spliced variants encoding different isoforms have been described. The heparin-binding growth factors are angiogenic agents in vivo and are potent mitogens for a variety of cell types in vitro. There are differences in the tissue distribution and concentration of these 2 growth factors. Fibroblast Growth Factor-2 Human Recombinant (FGF-2) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 155 amino acids and having a molecular mass of 17250 Dalton. Human FGF2 is purified by proprietary chromatographic techniques. Cat# BP07013
