Immunofluorescence analysis of PARP was performed using 70% confluent log phase HeLa cells treated with 1 uM staurosporine for 16 hours. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with PARP (Poly ADP-Ribose Polymerase) Rabbit Polyclonal Antibody (PA516561) at 2 ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing nuclear localization. Panel e shows untreated cells with no signal. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

PA5-16561 was successfully used to detect PARP in WB, IHC and IF applications.
PA5-16561 targets PARP (Poly ADP-Ribose Polymerase) in WB applications and shows reactivity with mouse, Rat, Bovine, and Human samples.
The PA5-16561 immunogen is a synthetic peptide from the C-terminal region of bovine PARP.
Poly ADP-Ribose Polymerase (PARP) uses nicotinamide adenine dinucleotide (oxidized form) NAD as a substrate to catalyse the transfer of ADP-ribose to a variety of nuclear protein acceptors. Proteolysis of PARP to its stable 85kDa fragment is an early marker of programmed cell death (apoptosis) and is mediated by the caspase CPP32 protein. Cleavage occurs between Adp216 and Gly217, a site in PARP conserved across species.
