Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

FGF19 (D1N3R) Rabbit mAb recognizes endogenous levels of total human FGF19 protein. This antibody does not cross-react with the mouse ortholog FGF15.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala148 of human FGF19 protein.

Background

FGF19 is a member of the large and diverse Fibroblast Growth Factor (FGF) family of peptide growth factors. FGF19 functions as a high affinity ligand for the FGF4 receptor, to which it binds in a heparin-dependent manner (1). Under normal physiological conditions, FGF19 is produced in the ileum when absorbed bile acids bind to the farnesoid X receptor (FXR), activating transcription of the FGF19 gene. FGF19 in turn functions in a negative feedback fashion to regulate bile acid synthesis (2). Consequently, disruptions in FGF19 signaling have been linked with clinical defects in bile acid synthesis, which may manifest as primary bile acid diarrhea or cholestasis (3,4). Research studies in oncology have shown that FGF19 can function in an endocrine, paracrine or autocrine fashion to promote tumorigenesis. In human studies, this has been demonstrated for breast cancer (5), gastric cancer (6) prostate cancer (7, 8), and hepatocellular carcinoma (9). Similar tumorigenic effects have been described for the mouse ortholog (Fgf15), notably in genetic models of hepatocellular carcinoma (10, 11)
