Immunogen
Immunogen:
Chemically synthesized peptide corresponding to N-terminus of cleavage site (214/215) of human PARP
Application Flow cytometry (10 μL per 10e6 cells).
Background Poly (ADP-Ribose) Polymerase (PARP) is a 116 kDa nuclear protein which is strongly activated by DNA strand breaks. During apoptosis, ICE family members, such as caspase-3 and -7, cleave PARP to yield an 85 kDa and a 25 kDa fragment. PARP cleavage is considered to be one of the classical characteristics of apoptosis.
Protocols Suggested Protocol for Induction of Apoptosis:
Apoptosis was induced by incubating Jurkat cells for 1 hour with 0.125 μg/mL anti-CD95/FAS antibody. The anti-PARP (214/215) FITC conjugated antibody has been shown to detect apoptosis when cells are treated with 1 μM camptothecin for 6 hours.

Suggested Staining Protocol:
After induction of apoptosis, wash cells 2 times with PBS/1% FCS. Fix cells by resuspending in 1 mL IC FixTM for 10 minutes at 4ºC then wash with PBS/0.1% sodium azide/1% FCS. The fixed cells can be stored at 4ºC for up to 7 days prior to staining. Aliquot fixed cells to a density of 10e6 cells/tube and wash 2 times in 1 mL IC PermTM. Pellet cells at 300 x g for 5 minutes, aspirate supernatant and resuspend in 40 μL IC PermTM. Add 10 μL anti-PARP (214/215) FITC and incubate at 4ºC for 30 minutes. Pellet cells and wash 2 times with 1 mL IC PermTM. Wash cells once in 1 mL PBS before resuspending the cells in 0.5 mL PBS, pH 7.3, for flow cytometric analysis.

Notes on Intracellular Staining Protocol:
At least one of the following specificity controls is recommended: 1) pre-incubating conjugated antibody with excess competing peptide; or 2) pre-incubating conjugated antibody with recombinant cleaved PARP.
High background staining has been reported for intracellular staining procedure. Increasing the concentration of non-specific protein (i.e., BSA or normal mouse serum) in IC PermTM to 2% may reduce this background staining.
In some cell lines, using 2 x IC PermTM buffer may increase the separation of positive and negative signals.

Solutions Used for Intracellular Staining Protocol:
IC FixTM
: 4% paraformaldehyde in 50 mM phosphate buffered saline, pH 7.3.
IC PermTM: 50 mM phosphate buffered saline, pH 7.3, 1% (v/v) fetal calf serum, 0.1% (w/v) sodium azide and 0.1% (w/v) saponin.

Storage Store the antibody at 2 - 8 °C up to one month or (in aliquots) at -20 °C for longer. Avoid repeated freezing and thawing.
Shelf life: one year from despatch.
Format
Label:
Fluorescein isothiocyanate
FITC
Purification:
Sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using a peptide spanning the cleavage site to remove antibody that is reactive with full length PARP. The final product is generated by affinity chromatography using a peptide corresponding to the PARP cleavage site.
Buffer System:
Phosphate buffered saline, pH 7.2, with bovine serum albumin, containing 0.09 % sodium azide as preservative
State:
Liquid Ig fraction
Specificity
Specificity:
This antibody specifically recognizes the 85 kDa fragment of cleaved PARP and can be used as a marker for detecting apoptotic cells.
Species:
Human, Bovine.
