• Product nameAnti-PADPR antibody
    See all PADPR primary antibodies
  • Description
    Chicken polyclonal to PADPR
  • SpecificityThis antibody recognizes PADPR synthesized by a variety of poly(ADP-ribose) polymerases (PARP)-related enzymes, including PARP1, 2, 3, tankyrase, vPARP, sPARP and others. It does not cross-react with ADP-ribose, 5'-AMP, or yeast RNA as tested by ELISA. It does cross-react to bovine serum albumin due to its use as a carrier for the immunogen.
  • Tested applicationsSuitable for: ICC/IF, IHC-Fr, WB, ELISA, IHC-Pmore details
  • Species reactivity
    Predicted to react with a wide range of species due to sequence homology.
  • Immunogen

    Purified PADPR mixed with methylated bovine serum albumin.



Our Abpromise guarantee covers the use of ab14460 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 1/200.
IHC-Fr Use at an assay dependent dilution.
WB Use a concentration of 1 - 10 µg/ml. Predicted molecular weight: 1 kDa.
ELISA Use at an assay dependent dilution. It is recommended to start with a 1/100 dilution.
IHC-P Use at an assay dependent dilution.


  • RelevancePADPR (Poly(ADP-ribose)) is a polymer synthesized by a class of enzymes named poly(ADP-ribose) polymerases (PARP). Using NAD+ as substrate, PARP catalyzes the formation of the polymer PADPR, with chain lengths ranging from 2 to 300 residues, containing approximately 2% branching in the chain. PADPR becomes attached to nuclear proteins, and to PARP itself (automodification). Under normal conditions, cells display low basal level of PADPR polymer, which can dramatically increase in cells exposed to DNA damaging agents (irradiation, alkylation, etc.). This increase of polymer synthesis is usually transient and is followed by a rapid degradation phase with a short half life which can be less than 1 min. The low endogenous level of polymer in unstimulated cells and its rapid catabolism during DNA damage has been ascribed to high activity of the polymer catabolizing enzyme poly(ADP-ribose) glycohydrolyase (PARG).

  • PADPR staining of untreated rat liver, with ab14460 at a concentration of 20µg/ml.

  • Predicted band size : 1 kDa

    Western blot analysis of PADPR. Lane 1: control HL60 cells (75,000 cells). Lane 2: cells automodified with PARP1. Note the apparent shift in molecular weight PARP1 from 116kDa to a broad range >250kDa due to various extents of PADPR automodification. ab14460 was used at a concentration of 10 µg/ml.
  • PADPR staining of livers from rats injected with diethylnitrosamine (200 mg/kg). The livers were removed and rapidly processed 10 hr later, at peak polymer induction. ab14460 was used at a concentration of 20µg/ml
  • ab14460 staining cultured human HeLa cells by ICC/IF.  Cells were PFA fixed and permeabilized in 0.5% Triton X100 prior to blocking in 5% BSA for 1 hour at 20°C.  The primary antibody was diluted 1/200 and incubated with the sample for 1 hour at 20°C.  A Cy5® conjugated donkey anti-chicken antibody diluted 1/300 was used as the secondary.
