Z-DEVD-pNA is a colorimetric substrate for caspase 3, a protease that is rapidly activated when cells are exposed to apoptotic conditions and that cleaves poly(ADP-ribose) polymerase. This substrate is hydrlyzed by caspase 3 to generate highly colored pNA that is measured at 405 nm by an absorption microplate reader or spectrophotometer.

Important notes

It is important to store at <-15 °C and should be stored in cool, dark place.

It can be used within 12 months from the date of receipt. 

PREPARATION OF STOCK SOLUTION

Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.

1. Z-DEVD-pNA stock solution (10 mM)
Prepare a 10 mM stock solution in DMSO.

PREPARATION OF WORKING SOLUTION

Prepare a 2X caspase substrate (50 μM) assay solution as the following:

ComponentVolume
Substrate stock solution50 µL
DTT (1M)100 µL
EDTA (100 mM)400 µL
Tris Buffer (20 mM), pH = 7.410 mL
 
Total volume10.55 mL

SAMPLE EXPERIMENTAL PROTOCOL

  1. Mix equal volume of the caspase standards or samples with 2X caspase substrate assay solution and incubate the solutions at room temperature for at least 1 hour.

  2. Monitor the fluorescence using a fluorescence microplate reader or absorbance using an absorbance microplate reader.
