FGF-2 (human) (rec.)

Human FGF-2 (aa 131-288) is untagged. Endotoxin Content: <0.1EU/?g purified protein (LAL test, Lonza). FGF-2 (Basic fibroblast growth factor) belongs to the FGF superfamily that is made up of 22 different fibroblast growth factor genes. FGF-2 and FGF-1 (acidic FGF) are unique in that they do not follow the conventional signal sequence for secretion. FGF-2 is found in five isoforms via alternative initiation of translation. Signaling of FGF-2 occurs through the high-affinity tyrosine kinase receptors FGFR1-4. FGF-2 is a potent wide-spectrum mitogen whose overexpression is associated with immortalization and unregulated cell proliferation in many tumors. FGF-2 functions in angiogenesis, cell survival, tissue repair, embryonic development and inflammation. FGF-2 is widely used to maintain the self-renewal of human embryonic stem cells (ESCs) and to induce pluripotent stem cells. FGF-2 is an established neurogenic factor for proliferation and differentiation of multipotent neural stem cells both during development and in the adult mouse brain as well.
