说明

一般說明

Recombinant, human basic fibroblast growth factor expressed in E. coli. A member of the FGF family of mitogenic peptides, comprised of seven related proteins showing 35-55% amino acid conservation within the family and 55% similarity with acidic FGF. Found in neuronal tissue (hippocampus, brain stem, peripheral ganglia, and the isocortex), pituitary, adrenal cortex, corpus luteum, and placenta. Some of the biological activities attributed to basic FGF include: mitogenic activity in vitro for cells of meso- and neuroectodermal origin (i.e. fibroblasts, endothelial cells, astrocytes, oligodendrocytes, neuroblasts, keratinocytes, bovine epithelial lens cells, osteoblasts, smooth muscle cells, and melanocytes); role in wound healing; induction of neuron differentiation, survival, and regeneration; chemoattractant effect and mitogenic activity in vitro for endothelial cells and angiogenic activity in vivo; role in tumor neovascularization. Inhibits DNA synthesis and alkaline phosphatase activity in rat osteosarcoma cell lines. Has been implicated in the development of Kaposi sarcoma in vitro. Inhibits iNOS in bovine retinal pigmented epithelial cells. Binding of FGF to heparin or cell surface heparin sulfate proteoglycans is necessary for FGF binding to its high affinity receptors. Basic and acidic FGF appear to bind to the same high affinity receptors and show a similar range of biological activities.

Recombinant, human basic fibroblast growth factor expressed in E. coli. Potent mitogen for bone cells. Inhibits DNA synthesis and alkaline phosphatase activity in rat osteosarcoma cell lines. Has been implicated in the development of Kaposi sarcoma in vitro. Inhibits inducible NOS in bovine retinal pigmented epithelial cells.
