Human FGF19 (Fibroblast Growth Factor 19) CLIA Kit (HUES00071)

Fibroblast Growth Factor 19 (FGF19) is an enterokine that regulates bile acid synthesis, glucose homeostasis, and hepatic lipid metabolism through activation of the FGFR4/β-Klotho receptor complex. Circulating FGF19 is widely investigated as a biomarker in studies of non-alcoholic fatty liver disease, primary bile acid diarrhea, and disorders of the gut–liver axis, where FXR-driven signaling is dysregulated.

This chemiluminescence-based immunoassay kit from Assay Genie is configured as a 96 assays pack and is intended for research use only. The chemiluminescent read-out delivers a broad dynamic range with low background, supporting quantitative work in human specimens where endogenous FGF19 concentrations are generally low. Reagents are supplied in vials and should be stored refrigerated; the kit includes standards, buffers, and detection components needed to complete a full plate run.

Beyond metabolic disease research, FGF19 measurement supports investigations into FXR pharmacology, intestinal inflammation, and liver regeneration biology. The CLIA format from Assay Genie fits translational laboratories comparing circulating FGF19 across cohorts, provided that sample handling and assay validation are carefully controlled.
