ELISA: Use at an assay dependent dilution. IHC-Fr: Use at a concentration of 5 - 20 μg/ml. WB: Use at a concentration of 2 μg/ml, if using ECL or 10 μg/ml, if using colorimetric methods. Optimal dilutions/concentrations should be determined by the end user.
Rat liver induced for PADPR synthesis by injection with diethylnitrosamine.
This antibody reacts with PADPR synthesized by a variety of poly(ADP- ribose) polymerases (PARP)-related enzymes including PARP1, 2, 3, tankyrase, vPARP, sPARP and others.The antibody does not cross-react with ADP-ribose, 5'-AMP, or yeast RNA as tested by ELISA.This antibody crossreacts to bovine serum albumin due to its use as a carrier for the immunogen.
Preservative: 0.02% Sodium Azide; Constituents: 1% BSA, 20mM Tris, 150mM Sodium Chloride. pH 7.4
Store as concentrated solution. Centrifuge briefly prior to opening vial. For short-term storage (1-2 weeks), store at 4ºC. For long-term storage, aliquot and store at -20ºC or below. Avoid multiple freeze-thaw cycles.

PADPR (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).
