Descripción

General description

Visfatin is also called pre-B cell colony enhancing factor, nicotinamide phosphoribosyltransferase, pre-B-cell colony-enhancing factor 1 homolog, NAmPRTase, Nampt and PBEF. Visfatin is an adipocytokine produced by visceral fat.

Biochem/physiol Actions

Visfatin has a role in mammalian nicotinamide adenine dinucleotide (NAD⁺) biosynthesis. Studies have shown that mice deficient in visfatin in the forebrain excitatory neurons show hyperactivity, diminished anxiety-like behaviors and impaired learning and memory. It has also been shown that visfatin stimulates glucose uptake and adenosine monophosphate-activated protein kinase (AMPK) phosphorylation in mouse C2C12 skeletal muscle cells.

Physical form

Lyophilized without any additives.

Reconstitution

Centrifuge the vial prior to opening. Avoid freeze-thaw cycles.

Reconstitute in PBS to the concentration of 0.1-1 mg/mL.
