Applications

Our Abpromise guarantee covers the use of ab221923 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
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
Flow Cyt Use at an assay dependent concentration.

ab199376 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

WB Use at an assay dependent concentration. Predicted molecular weight: 113 kDa.

Existing as a 113 kDa nuclear protein, PARP1 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)

Target

  • Function

    Involved in the base excision repair (BER) pathway, by catalyzing the poly(ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. This modification follows DNA damages and appears as an obligatory step in a detection/signaling pathway leading to the reparation of DNA strand breaks. Mediates the poly(ADP-ribosyl)ation of APLF and CHFR. Positively regulates the transcription of MTUS1 and negatively regulates the transcription of MTUS2/TIP150.
  • Sequence similarities

    Contains 1 BRCT domain.
    Contains 1 PARP alpha-helical domain.
    Contains 1 PARP catalytic domain.
    Contains 2 PARP-type zinc fingers.
  • Post-translational
    modifications

    Phosphorylated by PRKDC. Phosphorylated upon DNA damage, probably by ATM or ATR.
    Poly-ADP-ribosylated by PARP2. Poly-ADP-ribosylation mediates the recruitment of CHD1L to DNA damage sites.
    S-nitrosylated, leading to inhibit transcription regulation activity.
  • Cellular localization

    Nucleus.

     ab32138 was shown to react with PARP1 in wild-type HEK-293T cells in western blot. Loss of signal was observed when  knockout cell line ab266598 (knockout cell lysate ab257017). Wild-type HEK-293T and PARP1 knockout HEK-293T cell lysates were subjected to SDS-PAGE. ab32138 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively.

    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.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32138).
