Sequence
Met1-His491
Applicable Applications for NAMPT cell lysate
Western Blot (WB)
Application Notes
WB: Use at an assay dependent dilution.
Species
Human
Recommend Usage
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.2. Re-dissolve the pellet using 200uL pure water and boil for 2-5 min.
Sequence Construction
A DNA sequence encoding the human NAMPT (P43490) (Met 1-His 491 was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus.
Preparation Method
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors. Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Preparation and Storage
Store at 4 degree C for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80 degree C for up to twelve months. Avoid repeated freeze-thaw cycles.
Samples are stable for up to twelve months from date of receipt.
Related Product Information for NAMPT cell lysate
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 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.

This Human NAMPT overexpression lysate was created in Baculovirus-Insect cells and intented for use as a Western blot (WB) positive control. Purification of NAMPT protein from the overexpression lysate was verified.

NCBI Description

This gene encodes a protein that catalyzes the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, one step in the biosynthesis of nicotinamide adenine dinucleotide. The protein belongs to the nicotinic acid phosphoribosyltransferase (NAPRTase) family and is thought to be involved in many important biological processes, including metabolism, stress response and aging. This gene has a pseudogene on chromosome 10. [provided by RefSeq, Feb 2011]

Uniprot Description

PBEF: an ubiquitous protein originally described as a cytokine which acts on early B-lineage precursor cells. Other reports indicate that PBEF is not a cytokine-like secreted protein but an intracellular protein associated with the cell cycle. Contains a catalytically active nicotinate phosphoribosyltransferase domain, an enzyme involved in nicotinamide adenine dinucleotide (NAD) biosynthesis.

Product Notes

The NAMPT nampt (Catalog #AAA8114282) is a Cell Lysate produced from Baculovirus-Insect cells and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 728aa. AAA Biotech's NAMPT can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). WB: Use at an assay dependent dilution. Researchers should empirically determine the suitability of the NAMPT nampt for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: Met1-His49 1. It is sometimes possible for the material contained within the vial of "NAMPT, Cell Lysate" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
