Scientific Data Images for Human/Mouse/Rat PBEF/Visfatin Antibody

Detection of Human, Mouse, and Rat PBEF/Visfatin antibody by Western Blot.

Detection of Human, Mouse, and Rat PBEF/Visfatin by Western Blot.

Western blot shows lysates of 293T human embryonic kidney cell line, RAW 264.7 mouse monocyte/ macrophage cell line, Neuro-2A mouse neuroblastoma cell line, and Rat-2 rat embryonic fibroblast cell line. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human/Mouse/Rat PBEF/ Visfatin Monoclonal Antibody (Catalog # MAB40441) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for PBEF/Visfatin at approximately 52 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: PBEF/Visfatin

PBEF (pre-B cell colony-enhancing factor), also known as visfatin and nicotinamide phosphoribosyltransferase, is an approximately 52 kDa member of the NAPRTase family of molecules. It functions both intracellularly and extracellularly, where it participates in NAD synthesis and insulin receptor activation, respectively. Human PBEF is 491 amino acids in length and contains no signal sequence. There is at least one alternative splice form that shows a 5 aa substitution for the C-terminal 128 amino acids (aa 364-491). Over aa 27-491, human PBEF shares 96%, 97%, and 96% aa identity with mouse, porcine, and canine PBEF, respectively.
