产品介绍
Visfatin is a putative cytokine originally identified as PBEF (Pre-B cell-enhancing factor), subsequently determined to be a nicotinamide phosphoribosyltransferase (NAMPT) enzyme and member of the NAPRTase family, involved in catalyzing the biosynthesis of NAD from nicotinamide.Visfatin is highly expressed in bone marrow, muscle and liver tissue and increases in expression in response to endotoxin, in amniotic epithelial cells following lipopolysaccharide (LPS) stimulation, and during the activation of T and B cells, dendritic cells and macrophages, suggesting a role in inflammatory processes.

Target SpeciesHuman
Product FormPurified recombinant protein - lyophilized
PreparationPurified recombinant visfatin expressed inE.coli
ReconstitutionReconstitute with 0.25 ml distilled water. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.N.B. Due to solubility reasons, it is recommended that the solution be kept at low pH.
Buffer Solution10mM HCl
ActivityThe ED50was determined by the dose-dependant proliferation of the RPMI 8226 cells. The expected ED50for this effect is 15.0-20.0 ng/ml.
Preservative StabilisersNone present
Approx. Protein ConcentrationsTotal protein concentration 0.1 mg/ml after reconstitution
Protein Molecular Weight52.5 kDa (465 amino acid residues)
Purity>98% by SDS PAGE and HPLC analysis
RegulatoryFor research purposes only
GuaranteeGuaranteed for 3 months from the date of reconstitution or until the date of expiry, whichever comes first. Please see label for expiry date.
