Background: Nicotinamide phosphoribosyltransferase (NAMPT); also known as pre-B-cell colony-enhancing factor 1 (PBEF1) or visfatin; is an enzyme belonging to the family of glycosyltransferases; to be specific; the pentosyltransferases. This enzyme participates in nicotinate and nicotinamide metabolism. This enzyme catalyzes the condensation of nicotinamide with 5- phosphoribosyl-1- pyrophosphate to yield nicotinamide mononucleotide; one step in the biosynthesis of nicotinamide adenine dinucleotide. NAMPT is also considered as an essential enzyme mediating granulocyte colony-stimulating factor (G-CSF)-triggered granulopoiesis in healthy individuals and in individuals with severe congenital neutropenia. Intracellular NAMPT and NAD+ amounts in myeloid cells; as well as plasma NAMPT and NAD+ levels; were increased by G-CSF treatment of both healthy volunteers and individuals with congenital neutropenia.
Sequence: Met 1-His 491
Purity: > 90 % as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 8.0, 20% glycerol, 0.3mM DTT.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: Please refer to the printed manual for detailed information.
Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
