The Betatrophin protein, also known as the hepatocellular carcinoma-associated protein TD26, is an adipocyte- and liver-enriched insulin targeted gene that is thought to play a role in lipid metabolism be regulating serum triglyceride levels (1,2). Betatrophin is closely related to the angiopoietin-like (ANGPTL) protein family. Betatrophin mRNA increases in the cold environment and after treatment with a high-fat diet, while its mRNA levels decrease in response to fasting, suggesting that it may play a role in mediating thermogenesis and energy homeostasis (3).1) Ren G, Kim JY, and Smas CM.

Immunogen
Betatrophin antibody was raised against a 16 amino acid peptide near the amino terminus of human Betatrophin. The immunogen is located within amino acids 40 - 90 of Betatrophin.
Betatrophin antibody is human, mouse and rat reactive. At least three isoforms of Betatrophin are known to exist; this antibody will detect the two largest isoforms.
