PARP in vivo Pharmacodynamic Assay II

PARP catalyzes the NAD-dependent addition of poly (ADP-ribose) (PAR) onto itself and adjacent nuclear proteins. Furthermore, polymorphisms in the PARP-1 gene correspond to disease predisposition, and variation in PARP activity might have an impact on the effects of PARP inhibitors in clinical settings. To address the need to monitor PARP activity among different individuals, and within cells, Trevigen's improved validated PARP in vivo Pharmacodynamic Assay II measures net PAR levels in cellular extracts and has been used to document differences in PAR levels among tumor lysates from different tissues, organs and xenografts. The HT PARP in vivo Pharmacodynamic Assay II employs a purified, pre-coated monoclonal PAR antibody as the capture agent, and anti-PAR polyclonal rabbit antibody as the detecting agent.

Features:
  • Fewer user steps
  • Pre-coated 96 well capture antibody plates
  • High signal to noise ratio
  • Detection sensitivity of 2 pg/ml of PAR
  • Broad linear dynamic range to 1,000 pg/ml
  • Reduced inter-assay variability
  • Commercially available validated assay that measures drug action on PARP in both in vivo and in vitro settings
  •  
    Applications:
  • Quantification of PAR in peripheral blood mononuclear cells, tissue culture cells, and tumor lysates from different tissues, organs and xenografts.
  • Monitoring the efficacy of PARP inhibitors on PAR formation in vivo.
  • Verifying observations of enhanced cancer cell cytotoxicity arising from PARP inhibitor/anticancer drug combination therapy.
  • Facilitating development of PARP and PARG targeted therapeutics
