Anti-FGF2 antibodies are used in the immunodetection of the protein fibroblast growth factor 2. In humans, the canonical protein has a reported length of 288 amino acid residues and a mass of 30.8 kDa. Its subcellular localization is in the nucleus and is secreted. It is reported to be expressed in granulosa and cumulus cells. A member of the Heparin-binding growth factors protein family, FGF2 is known to act as a ligand for FGFR1, FGFR2, FGFR3 and FGFR4. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include FGFB, HBGF-2, basic fibroblast growth factor bFGF, fibroblast growth factor 2 (basic), heparin-binding growth factor 2, and BFGF. FGF2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 250 citations in the literature describe the use of FGF2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
