Anti-Fibroblast growth factor 21 Antibody

Produced by the liver and induced by fasting, Fibroblast growth factor 21 (FGF21) is an endocrine hormone that regulates glucose homeostasis, lipid metabolism, and ketogenesis. The Antibodies.com polyclonal primary antibody is raised in rabbit against human FGF21 and supplied unconjugated at 100 µg per vial, allowing laboratories to pair it with their preferred HRP, fluorescent, or chromogenic secondary detection systems.

Validated for Western blot (WB) and immunohistochemistry (IHC), the reagent detects endogenous FGF21 in cultured cells and tissue sections. Its polyclonal format offers multi-epitope recognition, supporting robust signal in samples where target expression may be low or variable. Reactivity is reported against human FGF21, making the antibody relevant to translational research into metabolic disorders such as type 2 diabetes, non-alcoholic fatty liver disease, and obesity.

FGF21 is increasingly studied as both a circulating biomarker and a therapeutic candidate in metabolic and endocrine research, where reliable antibody detection underpins studies of tissue distribution, signalling context, and hormone regulation under different physiological states.
