Rat Fibroblast Growth Factor 19 (FGF19) ELISA Kit

Endocrine regulation of bile acid synthesis, hepatic gluconeogenesis, and energy homeostasis depends on FGF19 (Fibroblast Growth Factor 19), a hormone-like signaling molecule primarily expressed in the distal ileum of the small intestine. This rat-reactive immunoassay from Assay Genie enables quantitative measurement of FGF19 across multiple specimen types relevant to metabolic and gastrointestinal research. The kit uses an absorbance-based detection method and is supplied in a 96 assays microplate format compatible with standard laboratory workflows. Reagents should be refrigerated upon arrival and the kit is intended for research use only. Each well plate supports studies of bile acid homeostasis, non-alcoholic fatty liver disease models in rodent systems, intestinal hormone crosstalk, and characterization of FGF15/FGF19 ortholog signaling. Researchers investigating hepatic glucose output, gallbladder and bile acid feedback loops, and metabolic disease mechanisms will find this kit useful for generating reproducible concentration data from rat-derived experimental samples.
