Fibroblast growth factor 19 (FGF-19) is a member of a subfamily of FGFs that includes FGF-21 and FGF-23, each member functions as an important regular of nutrient metabolism [1]. The primary source of endocrine FGF-19 is the ileum, bile acids release into the intestine after a meal to induce expression of FGF-19 [2]. Circulating FGF-19 plays an important role in maintaining proper bile acid homeostasis [3]. Several pharmacologic studies in hyperglycaemic, obese animal models have shown that FGF-19 can improve metabolic rate and lower serum glucose and hepatic triglyceride and cholesterol levels [4][5]. Like insulin, FGF-19 functions as postprandial hormone to govern hepatic protein synthesis, glycogen synthesis and gluconeogenesis, but does not stimulate lipogenesis [6].




The following standard curve is provided for demonstration only. A standard curve should be generated for each set of sample assay.


Human FGF-19 standard (4-parameter)




A. Sensitivity:

The lowest level of FGF-19 that can be measured by this assay is 15.6 pg/ml.


B. Specificity:

The antibodies used in this assay are specific to human FGF-19 and do not cross-react with human Adiponectin, FGF-21, FABP4, LCN2, RBP4 and PAI-1.


C. Precision:

Intra-assay Precision (Precision within an assay) C.V< 4.5%.

Inter-assay Precision (Precision between assays) C.V< 5.6%.
