Anti-FGF1 antibodies are used in the immunodetection of the protein fibroblast growth factor 1. In humans, the canonical protein has a reported length of 155 amino acid residues and a mass of 17.5 kDa. Its subcellular localization is in the nucleus, cytoplasm, and is secreted. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the kidney and brain. A member of the Heparin-binding growth factors protein family, FGF1 is known to play an important role in the regulation of cell survival, cell division, angiogenesis, cell differentiation and cell migration. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include AFGF and ECGF. FGF1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 70 citations in the literature describe the use of FGF1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
