Synthetic peptide (the amino acid sequence is considered to be commercially sensitive) within Human PARP (N terminal). The exact sequence is proprietary.
This product is a recombinant rabbit monoclonal antibody.
Produced using Abcam’s RabMAb® technology. RabMAb® technology is covered by the following U.S. Patents, No. 5,675,063 and/or 7,429,487.
A trial size is available to purchase for this antibody.
Our Abpromise guarantee covers the use of ab32138 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000 - 1/10000. Predicted molecular weight: 113 kDa.
Existing as a 113 kDa nuclear protein, PARP is cleaved between amino acids Asp214 and Gly215 to yield two fragments of 29 kDa (C-terminal catalytic domain) and 85 kDa (N-terminal DNA-binding domain)
ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
|ICC/IF||1/100 - 1/200.
Use with paraformaldehyde fixed cells.
Lane 1: Wild type HAP1 whole cell lysate (20 µg)
Lane 2: PARP1 knockout HAP1 whole cell lysate (20 µg)
Lane 3: HeLa whole cell lysate (20 µg)
Lane 4: MCF7 whole cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab32138 observed at 125 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab32138 was shown to specifically react with PARP1 when PARP1 knockout samples were used. Wild-type and PARP1 knockout samples were subjected to SDS-PAGE. Ab32138 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10 000 dilution respectively. Blots were developed with 800CW Goat anti Rabbit and 680CW Goat anti Mouse secondary antibodies at 1/10 000 dilution for 1 hour at room temperature before imaging.
ab32138 (1/200) staining PARP in HeLa cells (green). Cells were fixed in paraformaldehyde, permeabilised in 0.5% Triton X100/PBS and counterstained with DAPI in order to highlight the nucleus (red). For further experimental details please refer to Abreview.

Overlay histogram showing Jurkat cells stained with ab32138 (red line). The cells were fixed with methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab32138, 1/50 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1:500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit monoclonal IgG (0.5µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a decreased signal in Jurkat cells fixed with 4% paraformaldehyde (10 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.
