  • Product overview

    Abcam's FGF19 Human ELISA Kit (ab193703) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of human FGF19 in serum, plasma, and cell culture supernatants.

    This assay employs an antibody specific for human FGF19 coated on a 96-well plate. Standards and samples are pipetted into the wells and the immobilized antibody captures FGF19 present in the samples. The wells are washed and biotinylated anti-human FGF19 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 FGF19 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.

  • Function
    Involved in the suppression of bile acid biosynthesis through down-regulation of CYP7A1 expression, following positive regulation of the JNK and ERK1/2 cascades. Stimulates glucose uptake in adipocytes. Activity requires the presence of KLB and FGFR4.
  • Tissue specificity
    Expressed in fetal brain, cartilage, retina, and adult gall bladder.
  • Sequence similarities
    Belongs to the heparin-binding growth factors family.
  • Cellular localization
    Secreted.
