Our Abpromise guarantee covers the use of ab58640 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 10 µg/ml.
WB Use a concentration of 1.25 µg/ml. Detects a band of approximately 54 kDa (predicted molecular weight: 54 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use a concentration of 4 - 8 µg/ml.


  • Function

    Catalyzes the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, an intermediate in the biosynthesis of NAD. It is the rate limiting component in the mammalian NAD biosynthesis pathway.
  • Tissue specificity

    Expressed in large amounts in bone marrow, liver tissue, and muscle. Also present in heart, placenta, lung, and kidney tissues.
  • Pathway

    Cofactor biosynthesis; NAD(+) biosynthesis; nicotinamide D-ribonucleotide from 5-phospho-alpha-D-ribose 1-diphosphate and nicotinamide: step 1/1.
  • Sequence similarities

    Belongs to the NAPRTase family.
  • Cellular localization

  • Anti-Visfatin antibody (ab58640) at 1.25 µg/ml + Jurkat cell lysate at 10 µg with 5% skim milk in PBS buffer

    HRP conjugated anti-Rabbit IgG at 1/50000 dilution

    Predicted band size: 54 kDa
    Observed band size: 54 kDa

    Gel concentration: 12%
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human kidney tissue labelling Visfatin with ab58640 at 4-8µg/ml. Arrows indicate positively labelled epithelial cells of the renal tubules. Magnification: 400X.

  • ICC/IF image of ab58640 stained HepG2 cells. The cells were 4% formaldehyde (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab58640, 10µg/ml) overnight at +4°C. The secondary antibody (green) was for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for your call yesterday and for your email.

I'm sending a free of charge vial of ab58640 on the order ***, which should arrive tomorrow. This vial is from the same production batch as the first vial that you used in 2009 so I'm hopeful that it will work in a similar way.

I would like to follow-up with the lab so we can investigate the problem with the other lots that you have used. Could you send me some details of the protocols that you have used? In particular it would be helpful to know:

1) Species and tissue type tested with the antibody
2) Sample preparation (fixation, permeabilization, antigen retrieval)
3) Dilution/concentration of the antibody and incubation time
4) Blocking solution (for example, BSA or serum)
5) Detection system

Please keep me updated about the results using the new vial, and let me know if you have any questions or if there is anything else that we can do for you.
