The following Fibroblast Growth Factor 19 ELISA kits are useful research tools for the measurement of fibroblast growth factor 19 in biological samples. In humans this protein is encoded by the FGF19 gene. 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 has been described to be a secreted protein. In addition, it is reported to be expressed in fetal brain, cartilage, retina, and adult gall bladder.
Some fibroblast growth factor 19 ELISA kits can detect targets at levels as low as 0.39 pg/mL and as high as 20 ng/mL. Use the search filters to narrow your search and click on the ELISA kits below for more detailed information, such as reactivity and assay sensitivity.
