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. (Ac-IETD)₂-R110 stock solution (10 mM):
Add 75 µL of DMSO into the vial of 1 mg (Ac-IETD)₂-R110 to make 10 mM stock solution.

PREPARATION OF WORKING SOLUTION

Caspase 8 assay solution (2X):
Mix 50 µL (Ac-IETD)₂-R110 stock solution (10 mM), 100 µL DTT (1M), 400 µL EDTA (100 mM) and 10 mL Tris Buffer (20 mM), pH =7.4.

SAMPLE EXPERIMENTAL PROTOCOL

Mix equal volume of the caspase 8 standards or samples with 2X caspase 8 assay reaction solution and incubate at room temperature for at least 1 hour.
Monitor the fluorescence increase at Ex/Em = 490/525 nm.
