The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesELISA: This antibody can be used as a solution phase antibody at 2 µg/ml in a two site ELISA with unconjugated FGF basic antibody. Typically the ELISA has a working range of 0-2000 pg/ml and a sensitivity of 5 pg/ml with the appropriate standard. Recovery of human basic FBF is human serum is typically >85% in the ELISA.
Not tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionPlays an important role in the regulation of cell survival, cell division, angiogenesis, cell differentiation and cell migration. Functions as potent mitogen in vitro. Can induce angiogenesis (PubMed:23469107).
Tissue specificityExpressed in granulosa and cumulus cells. Expressed in hepatocellular carcinoma cells, but not in non-cancerous liver tissue.
Sequence similaritiesBelongs to the heparin-binding growth factors family.
Post-translational modificationsPhosphorylation at Tyr-215 regulates FGF2 unconventional secretion. Several N-termini starting at positions 94, 125, 126, 132, 143 and 162 have been identified by direct sequencing.
Cellular localizationSecreted. Nucleus. Exported from cells by an endoplasmic reticulum (ER)/Golgi-independent mechanism. Unconventional secretion of FGF2 occurs by direct translocation across the plasma membrane. Binding of exogenous FGF2 to FGFR facilitates endocytosis followed by translocation of FGF2 across endosomal membrane into the cytosol. Nuclear import from the cytosol requires the classical nuclear import machinery, involving proteins KPNA1 and KPNB1, as well as CEP57.
