特徴

• Acidic fibroblast growth factor 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.
• Source:Recombinant protein corresponding to human Fibroblast Growth Factor-acidic, a single non-glycosylated polypeptide chain containing 140aa, expressed in E. coli.
• Molecular Weight:~15.8kD (140aa)
• Applications:Suitable for use in SDS-PAGE. Other applications not tested.
• Recommended Dilution:Optimal dilutions to be determined by the researcher.
