Recognizes poly(ADP-ribose) polymer (pADPr) synthesized by a variety of poly(ADP-ribose) polymerases (PARP)-related enzymes including PARP-1, -2, -3, tankyrase, vPARP, sPARP and others. Uses for the clone 10H monoclonal antibody include Western blotting, immunostaining, ELISA-based PARP activity screen, and immunodot blot.
Note: Not all species have been tested for usefulness with this product. Only those species listed have been tested. We cannot make any guarantees about additional reactivities which may or may not occur.
Poly(ADP-ribose) mixed with methylated bovine serum albumin.
Localization:
Nuclear and cytoplasmic
Species Reactivity:
Reacts with Poly ADP-ribose polymer. Does not crossreact 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.
Applications:
Uses:
Western Blot (10 ug/ml using colorimetric
methods).
Dilutions:
ELISA ,
immunohistochemistry 5-20 ug/ml,
Western Blot 2 ug/ml,
Immunocytochemistry 5-20 ug/ml,
Aliquot and store at -20 °C or -80 °C. Avoid freeze-thaw cycles.
Buffer:
20 mM Tris, pH 7.4, 150 mM NaCl, 1% BSA
Preservative:
0.02% Sodium Azide
Limitations:
This product is for research use only and is not approved for use in humans or in clinical diagnosis. Products are guaranteed for 6 months from date of receipt, except for peptides and proteins which are guaranteed for 3 months.
Poly(ADP-ribose) or "pADPr" is a polymer synthesized by a class of enzymes named poly(ADP-ribose) polymerase's (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).
Poly(ADP-ribose) staining of rat liver. Rats were injected i.p. with diethylnitrosamine (200 mg/kg), and the livers were removed and rapidly processed 10 hr later, at peak polymer induction (DEN). Control was untreated liver. Tissue were stained according to the above protocol using anti-pADPr clone 10H. (courtesy J.B. Kirkland, Univ. Guelph, Canada)
