Technical Data
PBEF (Pre-B cell Colony Enhancing Factor, Pre-B cell Enhancing Factor, 1110035O14Rik, DKFZP666B131, EC, MGC117256, Nicotinamide Phosphoribosyltransferase, NAmPRTase, NAMPT, Pre-B cell Colony Enhancing Factor 1, PBEF1, Visfatin)
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.

Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1:1000-1:3000
Optimal dilutions to be determined by the researcher.

FO myeloma cells with spleen cells from Balb/c mice.
