ChIP Validated Western Blot Validated Immunoprecipitation Validated Immunofluorescence Validated

Application Notes

Validated Applications:
ChIP: 2 - 10 µl per ChIP
IP: 2 - 10 µl per IP
WB: 1:500 dilution

The addition of 0.05% Tween 20 in the blocking buffer and primary antibody incubation buffer is recommended to aid in detection by Western blot. Individual optimization may be required.

Validated Applications:


This PARP-2 antibody was raised against a recombinant protein corresponding to the C-terminal region of human PARP-2.


Purified IgG in 70 mM Tris (pH 8), 105 mM NaCl, 31 mM glycine, 0.07 mM EDTA, 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.

Lane 1: U2OS nuclear extract (20 µg). Lane 2: A549 whole-cell extract(20 µg). Lane 3: Hep G2 whole-cell extract (20 µg). Lane 4: Jurkat cell nuclear extract (20 µg). These were probed with PARP-2 antibody at a dilution of 1:500.


PARP-2 encodes a chromatin-associated enzyme, a poly-ADP ribosyl transferase, which modifies various nuclear proteins by poly-ADP ribosylation. The modification is dependent on DNA and is involved in the regulation of various important cellular processes such as differentiation, proliferation and tumor transformation. It also plays a role in the regulation of the molecular events involved in the recovery of cells from DNA damage. PARP-2 is cleaved by caspase enzymes during the process of apoptosis.

Positive Control

Active Motif's Hep G2 whole-cell extract (Catalog No. 36412) can be used as a positive control for PARP-2 antibody.

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
