Specifications

bFGF is a single-chain polypeptide growth factor that plays a significant role in the process of wound healing and is a potent inducer of angiogenesis. Several different forms of the human protein exist ranging from 18-24 kD in size due to the use of alternative start sites within the fgf-2 gene. It has a 55 percent amino acid residue identity to FGF-1 and has potent heparin-binding activity. The growth factor is an extremely potent inducer of DNA synthesis in a variety of cell types from mesoderm and neuroectoderm lineages. It was originally named basic fibroblast growth factor based upon its chemical properties and to distinguish it from acidic fibroblast growth factor.Other homologous FGF belonging to the same family are int-2 ( FGF-3 ), FGF-5 , FGF-6 , K-FGF and KGF ( keratinocyte growth factor =FGF-7 ). All factors are products of different genes, some of which are Oncogene products ( FGF-3 , FGF-4 , FGF-5 ).
