• Reactivity: Human
• Applications: E, WB, SDS-PAGE, MS
• Delivery Time: Ship in 1 week
• Form: Lyophilized from a 0.2 μm filtered solution of 20mM HEPES, 150mM NaCl, pH8.0.
• Gene Symbol: NAMPT
• Alternative Names: PBEF; PBEF1; Nicotinamide phosphoribosyltransferase; NAmPRTase; Nampt; Pre-B-cell colony-enhancing factor 1; Pre-B cell-enhancing factor; Visfatin
• Entrez Gene (Human): 10135.0
• SwissProt (Human): P43490
• Purity: Greater than 95% as determined by reducing SDS-PAGE.
• Quality Control: Endotoxin: Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.
• Directions for Use: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• Storage/Stability: Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
