Description Visfatin is pre-B cell colony-enhancing factor 1(PBEF), which is predominantly secreted from visceral adipose tissue both in humans and mice. This protein has also been reported to be a cytokine (PBEF) that promotes B cell maturation and inhibits neutrophil apoptosis, or a visceral-fat derived hormone that acts by binding and activating the insulin receptor. Source: Recombinant protein corresponding to aa1-491 of human Visfatin, fused to His-tag at N-terminal expressed in E. coli.
