Mouse anti poly (ADP-ribose) polymerase 1 antibody, clone A6.4.12 used to immunolocalize PARP-1 expression in normal and Alzheimer's diseased brain by immunohistochemistry on formalin fixed paraffin embedded tissue sections.
Image caption:
Nucleolar PARP-1 immunoreactivity in AD ranged from absent to dispersed and less intense compared to that of controls. ((a) and (b)) Representative immunostaining with diaminobenzidine (DAB) of human hippocampal pyramidal neurons in CA1 region. (a) Prominent nucleolar staining of PARP-1 (arrows) was seen in most of pyramidal neurons of a control case. (b) The nucleolar staining of PARP-1 ranged from absent (arrowheads) to a more dispersed pattern with less intensity of label (arrows) in pyramidal neurons of an AD case.

Image caption:
PARP-1 nucleolar immunoreactivity is altered in hippocampal pyramidal cells in AD brains. Representative confocal microscopy of PARP-1 immunostaining (red) with DAPI nuclear counterstaining (blue) of CA4 hippocampal pyramidal neurons. In controls brains (a–c) a high percentage of pyramidal cell nucleoli have intense and well- delineated PARP-1 staining (arrowheads). In contrast, in AD brains (d–f), the percentage of intensely stained and well-delineated nucleoli is less than in the controls and there is a more dispersed pattern with weak label intensity ((d) and (f), arrow). ((g) and (h)) The percentage of CA1 (g) and CA4 (h) hippocampal pyramidal neurons with PARP-1 positive nucleoli staining was less in AD cases compared to controls. (Control, and for CA1 and CA4, resp.; AD, for both CA1 and CA4; .) Scale bar = 25 μM.

Image caption:
Nucleolar proteins in hippocampal pyramidal cells are altered in AD. ((a)–(h)) Representative figures show colocalization ((d) and (h), yellow) of fibrillarin ((b) and (f), green) and PARP-1 ((c) and (g), red) in the nucleoli of pyramidal neurons. Control cases exhibit high intensity staining (a–d) compared to AD (e–h) (arrowheads). In AD compared to controls, there is a lower percentage of nucleoli that are both PARP-1(+) and fibrillarin(+) ((f)-(g), arrowhead) in CA1 (see Table 2) and CA4 (see Table 3) pyramidal cells and a higher percentage of nucleoli PARP-1(−)/fibrillarin(+) ((f) and (g), arrow) in CA1 (see Table 2) and CA4 (see Table 3), suggesting that different nucleolar proteins are affected in different ways in AD. Scale bar = 20 μm.

Mouse anti poly(ADP-ribose) polymerase-1 antibody, clone A6.4.12 (MCA1522G) used for the evaluation of PARP-1 expression in murine neural stem/progenitor cell populations by western blotting.
Image caption:
Higher amounts of p53 protein and phosphorylated p53 in NSPCs after PARP inhibition. a Cleaved fragments of caspase-3 (p17) and caspase-8 (p43/p41/p18) were clearly detectable by western blotting with specific antibodies. The cleaved fragment of pro-caspase-9 (p37) was also detectable, although the band density of this fragment was low. b Phase-contrast images were shown on the top. Higher amounts of p53 protein and phosphorylated p53 in NSPCs after PARP inhibition were also revealed by immunocytochemistry. Representative images from 4 separate experiments are shown. c Western blot analysis demonstrated that PARP-1 was abundant and activated in NSPCs in contrast to MEFs. Amounts of p53 protein and phosphorylated p53 at Ser 18 were remarkably increased by PJ34. Scale bars in (b), 20μm.

Image caption:
Levels of H2O2-induced ADP-ribosylation and XRCC1 recruitment into chromatin in PARP-deleted RPE-1 cells. (A) Levels of the indicated proteins (left) and ADP-ribosylated proteins (right) were compared in cell lysates from the indicated WT or mutant RPE-1 cells harvested before and after treatment with 400 μM H2O2 for 7 min by Western blotting using appropriate antibodies and anti-pan-ADP-ribose binding reagent. (B) Levels of ADP-ribosylation and chromatin-bound XRCC1 were analysed by indirect immunofluorescence in cells treated or not with H2O2 (as above) by fixation and staining with anti-pan-ADP-ribose binding reagent (top panels) or by detergent pre-extraction prior to fixation and staining with anti-XRCC1 antibody (bottom panels). Representative ScanR images are shown.

Antibody Quality and Performance Guarantee
| Mouse anti poly (ADP-ribose) polymerase 1 antibody, clone A6.4.12 recognizes poly (ADP-ribose) polymerase 1 (PARP-1), a ~116 kDa nuclear enzyme, cleaved during apoptosis (Soldani et al. 2002). PARP-1, a caretaker enzyme, is involved in DNA damage repair (Langelier et al. 2013), plays roles in diabetes pathophysiology (Andreone et al. 2012) and tumour proliferation ( As well as protecting cells from genomic instability, PARP-1 is involved in the development of both inflammatory and immune responses, and cell death by apoptosis and necrosis (Erdélyi et al. 2005). Mouse anti poly(ADP-ribose) polymerase 1 antibody, clone A6.4.12, targets PARP-1, an enzyme which represents a promising target for new developments in therapeutic treatment of immune mediated diseases ( |
