Nampt (Visfatin/PBEF) (mouse) (rec.) (His)
10μg/ml Nampt (mouse) (rec.) (His) (Prod. No. AG-40A-0017) or human insulin was added to differentiating 3T3-L1 cells that had been stimulated with 1μM dexamethasone and 0.5mM IBMX for 2 days. After 5 days, fat droplets were stained with Oil-Red O.

Nicotinamide phosphoribosyltransferase (Nampt; pre-B cell colony-enhancing factor; PBEF; Visfatin) is an adipokine that is localized to the bloodstream and has various functions, including the promotion of vascular smooth muscle cell maturation and inhibition of neutrophil apoptosis. It activates insulin receptor and has insulin-mimetic effects, lowering blood glucose and improving insulin sensitivity. The protein is highly expressed in visceral fat and serum levels of the protein correlate with obesity. Recently NAMPT extracellular (eNAMPT) has been shown to be secreted from macrophages in muscles and to triggers a proliferative signal of muscle stem cell (MusC) by binding to CCR5 located at the surface receptor of MusC.
