Polyclonal Antibody against Human FGF-19
Size: 0.1 mg
Introduction
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 regulator 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 hyperglycemic, 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].
Purification
Antigen affinity-purified
Immunogen
Recombinant full-length human FGF-19 expressed in E.coli.
Specificity
The antibody detects circular human FGF-19.
Formulation
Liquid in phosphate-buffered saline (PBS).
Storage
Store at –20°C for less than one week. For long-term storage, aliquot and freeze at -70°C. Avoid repeated freeze/defrost cycles.
Application/Usage
ELISA - the antibody can be used as capture and detection antibody in ELISA.
