FGF19 ELISA kits are immunoassay tools for the measurement of the protein fibroblast growth factor 19, which is encoded by the FGF19 gene in humans. Functionally, this protein is reported to be involved in suppression of bile acid biosynthesis through down-regulation of CYP7A1 expression, following positive regulation of the JNK and ERK1/2 cascades. The canonical protein structure is reported to have an amino acid length of 216 residues, a mass of 24 kDa, and is a member of the Heparin-binding growth factors protein family. It is known to be secreted and is reported to be expressed in fetal brain, cartilage, retina, and adult gall bladder.
Some FGF19 ELISA kits can detect targets at levels as low as 0.53 pg/mL and as high as 500 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
