• Formulation Lyophilized from a 0.2 μm filtered solution in PBS, pH 7.4.
• Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg mL. Stock solutions should be apportio
• Storage This lyophilized preparation is stable at 2-8 ˚C, but should be kept at -20 ˚C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 ˚C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 ˚C to -70 ˚C. Avoid repeated freeze thaw cycles.

Murine bFGF, encoded by the FGF2 gene, is a member of the fibroblast growth factor (FGF) family. Fibroblast growth factor was found in pituitary extracts in 1973 and then tested in a bioassay that caused fibroblasts to proliferate. After further fractionating the extract using acidic and basic pH, two different forms have isolated that named "acidic fibroblast growth factor" (FGF-1) and "basic fibroblast growth factor" (FGF-2). Murine bFGF shares 95 % amino acid sequence identity with human bFGF. Affinity between bFGF and its receptors can be increased by heparin or heparan sulfate proteoglycan. bFGF plays an important role in the regulation of cell survival, cell division, angiogenesis, cell differentiation and cell migration. bFGF are also involved in a variety of biological processes, including embryonic development , morphogenesis, tissue repair, tumor growth and invasion. Additionally, bFGF is frequently used for a critical component of cell culture medium, e.g., human embryonic stem cell culture medium, serum-free culture systems.
