Our Abpromise guarantee covers the use of ab45890 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use at an assay dependent concentration.
Use a concentration of 10 µg/ml.
|WB||1/250. Detects a band of approximately 56 kDa (predicted molecular weight: 56 kDa).|
FunctionCatalyzes 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 specificityExpressed in large amounts in bone marrow, liver tissue, and muscle. Also present in heart, placenta, lung, and kidney tissues.
PathwayCofactor biosynthesis; NAD(+) biosynthesis; nicotinamide D-ribonucleotide from 5-phospho-alpha-D-ribose 1-diphosphate and nicotinamide: step 1/1.
Sequence similaritiesBelongs to the NAPRTase family.

ICC/IF image of ab45890 stained HeLa cells. The cells were 100% methanol fixed (5 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 ab45890 at 10µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution 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.
ab45890 staining PBEF in rat brain tissue section by Immunohistochemistry (PFA perfusion fixed frozen sections). Tissue from 4% PFA perfused animals underwent overnight fixation in 4% paraformaldehyde, cryoprotected in 30% sucrose and cut using cryostat.The primary antibody was diluted, 1/1000 (PBS + 0.3% Triton X100) and incubated with sample for 18 hours at 20°C. An abcam antibody ab60314, Chromeo488 conjugated goat polyclonal to rabbit IgG was used as secondary, at 1/1000 dilution.
This antibody produces a nice staining in rat cortical neurons. Some tracts of fibers were stained as well. The picture shows the staining obtained in cortical neurons.
