Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (ET1608-56) at 1/2,000 dilution and competitor's antibody at 1/1,000 dilution were used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1:50,000 dilution was used for 1 hour at room temperature.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (ET1608-56) at 1/2,000 dilution was used in 5% NFDM/TBST at 4℃ overnight.

	Fig3: All lanes: Western blot analysis of PARP with anti-PARP1 antibody[SU03-68] (ET1608-56) at 1:500 dilution. Lane 1/2: Wild-type Hela whole cell lysate (10 µg). Lane 3/4: PARP knockdown Hela whole cell lysate (10 µg). ET1608-56 was shown to specifically react with PARP in wild-type Hela cells. Weakened bands were observed when PARP knockdown samples were tested. Wild-type and PARP knockdown samples were subjected to SDS-PAGE. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM in TBST for 1 hour at room temperature. The primary antibody (ET1608-56, 1/500) was used in 5% BSA at room temperature for 2 hours. Goat Anti-Rabbit IgG-HRP Secondary Antibody (HA1001) at 1:200,000 dilution was used for 1 hour at room temperature.
	Fig4: Immunocytochemistry analysis of HeLa cells labeling PARP1 with Rabbit anti-PARP1 antibody (ET1608-56) at 1/500 dilution. Cells were fixed in 100% methanol for 5 minutes, blocked with 2% normal goat serum for 30 minutes at room temperature. Cells were then incubated with Rabbit anti-PARP1 antibody (ET1608-56) at 1/500 dilution in 2% normal goat serum overnight at 4 ℃. Nuclear DNA was labelled in blue with DAPI. Beta tubulin (M1305-2, green) was stained at 1/200 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 488, HA1125) was used as the secondary antibody at 1/800 dilution.

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 2 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH₂O and PBS, and then probed with the primary antibody (ET1608-56) at 1/4,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Cells were fixed and permeabilized. Then stained with the primary antibody (ET1608-56, 1/1,000) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody (HA1121) at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
