    Specificity / Sensitivity

    PARP (46D11) Rabbit mAb detects endogenous levels of total full-length PARP and the large fragment (89 kDa) produced by caspase cleavage.

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly623 of PARP.

    Western Blotting

    Western Blotting

    Western blot analysis of extracts from THP-1 cells, untreated or treated with TNF-α and cycloheximide as well as control extracts from SW620 and A20 cell lines, using PARP (46D11) Rabbit mAb.

    IF-IC

    IF-IC

    Confocal immunofluorescent analysis of untreated HeLa cells labeled with PARP (46D11) Rabbit mAb (green). Actin filaments have been labeled with Alexa Fluor® 555 phalloidin (red).

    Background

    PARP, a 116 kDa nuclear poly (ADP-ribose) polymerase, appears to be involved in DNA repair in response to environmental stress (1). This protein can be cleaved by many ICE-like caspases in vitro (2,3) and is one of the main cleavage targets of caspase-3 in vivo (4,5). In human PARP, the cleavage occurs between Asp214 and Gly215, which separates the PARP amino-terminal DNA binding domain (24 kDa) from the carboxy-terminal catalytic domain (89 kDa) (2,4). PARP helps cells to maintain their viability; cleavage of PARP facilitates cellular disassembly and serves as a marker of cells undergoing apoptosis (6).
