PARP/Apoptosis Colorimetric Assay Kit


The PARP/Apoptosis Colorimetric Assay Kit is ideal for measuring the in vitro activity of PARP-1 in cell extracts before and during apoptosis, screening of candidate PARP-1 inhibitors and determination of IC50 values.

Available Size(s): 96 tests Catalog Number: 4684-096-K Category:


This ELISA based assay detects poly (ADP-ribose) deposited by PARP-1 onto immobilized histones in a 96-well format. An anti-PAR monoclonal detecting antibody followed by addition of a goat anti-rabbit IgG-HRP secondary and a colorimetric HRP substrate yields relative absorbance that correlates with PARP-1 activity.  During apoptosis PARP-1 is cleaved with a resulting drop in activity. Etoposide is included as a control apoptosis inducer.


  • Colorimetric readout
  • 96 well format
  • Highly sensitive – detects 0.1 mU PARP ~500 cells
  • Dynamic range between 0.1 to 10 mU PARP
  • Requires 10-100 ng extract for detection
  • Assay Time ~3 hrs


  • Measure PARP-1 activity in cell extracts before and after apoptosis.
  • For the screening of candidate PARP-1 inhibitors and determination of IC50 values.
