Protein Family: Enzymes
Pathway and Disease: Cofactor and Vitamin Metabolism
Alternate Names: Visfatin, Pre-B-cell colony enhancing factor 1, PBEF, Nicotinamide phosphoribosyltransferase, NAmPRTase, NAMPTDescription:
Visfatin is an adipokine produced by visceral adipose tissue. Other adipokines include leptin, adiponectin, resistin, chemerin, omentin and vaspin. Visfatin has been shown to act as a pro-inflammatory factor for PBMCs and may mimic the effects of insulin on adipocytes, monocytes and hepatocytes. Human Visfatin is produced in E.coli. Recombinant human Visfatin is a non-glycosylated protein, containing 466 amino acids, with a molecular weight of 52.6 kDa.
Source: E. coli. Endotoxin level as measured by LAL is <0.05ng/ug or <0.5EU/ug.
Applications: E, WB
Application Notes:
The activity is determined by its ability to induce IL-6, IL-1 beta and TNF alpha production from human PBMCs at 100 ng/mL. Specific activity: 1 x 10e4 units/mg
Accession No.: P43490
MW: 52600 Da

Purity:
Purity > 95% as determined by RP-HPLC and reducing and non-reducing SDS-PAGE. Protein Content determined by UV spectroscopy at 280 nm and analysis by RP-HPLC calibrated against a known standard. Quantitation on SDS-PAGE against a known standard.
Format:
Each vial contains 25 ug of lyophilized protein. Reconstitute with 0.25 ml sterile deionized water for a final concentration of 0.1 mg/ml.
Storage: Store at -20°C. Product is guaranteed one year from the date of shipment. Following reconstitution, store at -20°C. We recommend to add a carrier protein (0.1% HSA or BSA) for long term storage.
