Fibroblast growth factor-1 (FGF-1), also designated acidic FGF, and fibroblast growth factor-2 (FGF-2), also designated basic FGF, are members of a family of growth factors that stimulate proliferation of cells of mesenchymal, epithelial and neuroectodermal origin. Additional members of the family include the oncogenes FGF3 (Int2) and FGF4 (hst/Kaposi), FGF5, FGF6, FGF7 (KGF), FGF8 (AIGF), FGF9 (GAF) and FGF10 through FGF-23. Members of the family share 30-55% amino acid sequence identity and similar gene structure, and are capable of transforming cultured cells when overexpressed in trans- fected cells. Cellular receptors for FGFs are members of a second multigene family, including four tyrosine kinases designated Flg (FGFR-1), Bek (FGFR-L), TKF and FGFR-3.

Store the FGF-23 antibody at 2-8°C (with azide) or aliquot and store at -20°C or colder (without azide).
