  • Product overview

    Abcam’s aFGF (acid FGF) Human ELISA Kit (ab193691) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human aFGF in serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for human aFGF coated on a 96-well plate. Standards and samples are pipetted into the wells and aFGF present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-human aFGF antibody is added. After washing away any unbound biotinylated antibody, an HRP-conjugated streptavidin is pipetted to the wells. After incubation, the wells are again washed, followed by the addition of a TMB substrate solution to the wells. Color will develop in proportion to the amount of aFGF bound in each well. Addition of the Stop Solution will change the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Research areas

  • Function

    Plays an important role in the regulation of cell survival, cell division, angiogenesis, cell differentiation and cell migration. Functions as potent mitogen in vitro.
  • Tissue specificity

    Predominantly expressed in kidney and brain. Detected at much lower levels in heart and skeletal muscle.
  • Sequence similarities

    Belongs to the heparin-binding growth factors family.
  • Post-translational

    In the nucleus, phosphorylated by PKC/PRKCD.
  • Cellular localization

    Secreted. Cytoplasm. Cytoplasm > cell cortex. Cytoplasm > cytosol. Nucleus. Lacks a cleavable signal sequence. Within the cytoplasm, it is transported to the cell membrane and then secreted by a non-classical pathway that requires Cu(2+) ions and S100A13. Secreted in a complex with SYT1 (By similarity). Binding of exogenous FGF1 to FGFR facilitates endocytosis followed by translocation of FGF1 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 LRRC59.
