PARP/Apoptosis Colorimetric Assay Kit Summary

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.

Key Benefits

• 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

Why Use the PARP/Apoptosis Colorimetric Assay Kit?

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.
