Our Cell Meter™ assay kits are a set of tools for monitoring cell viability. There are a variety of parameters that can be used for monitoring cell viability. This particular kit is designed to monitor cell apoptosis through measuring Caspase 3 activation. Caspase 3 is widely accepted as a reliable indicator for cell apoptosis since the activation of caspase-3 (CPP32/apopain) is important for the initiation of apoptosis. Caspase 3 has substrate selectivity for the peptide sequence Asp-Glu-Val-Asp (DEVD). This kit uses Z-DEVD-ProRed™ as the fluorogenic indicator for caspase-3 activity. Cleavage of ProRed™ DEVD blocking peptide residue by caspase 3 generates strongly red fluorescent ProRed™ that is monitored fluorimetrically at ~620 nm with excitation of ~530 nm. The kit provides all the essential components with an optimized assay protocol. The assay is robust, and can be readily adapted for high-throughput assays. Using 100 uL of reagents per well in a 96-well format, this kit provides sufficient reagents to perform 100 assays. Using 25 uL of reagents per well in a 384-well format, this kit provides sufficient reagents to perform 400 assays.

Protocol summary
- Prepare cells with test compounds (100 µL/well/96-well plate or 25 µL/well/384-well plate)
- Add equal volume of Caspase 3/7 Substrate working solution (100 µL/well/96-well plate or 25 µL/well/384-well plate)
- Incubate at room temperature for 1 hour
- Monitor fluorescence intensity (top or bottom read mode) at Ex/Em = 540/620 nm (Cutoff = 610 nm)
Important notes
Thaw all the kit components at room temperature before starting the experiment.
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-ProRed™ stock solution (200X):
Add 65 µL of DMSO into the vial of Z-DEVD-ProRed™ (Component A) to make 200X Z-DEVD-ProRed™ stock solution. Protect from light.
PREPARATION OF WORKING SOLUTION
Add 50 μL of 200X Z-DEVD-ProRed™ stock solution into 10 mL of Assay Buffer (Component B) and mix well to make Caspase 3/7 Substrate working solution. Note: Aliquot and store the unused Z-DEVD-ProRed™ Stock solution (from Step 2.2) and Assay Buffer (Component B) at -20 oC. Avoid repeated freeze/thaw cycles.
SAMPLE EXPERIMENTAL PROTOCOL
Prepare cells:
- For adherent cells: Plate cells overnight in growth medium at 20,000 cells/well/90 uL for a 96-well or 5,000cells/well/ 20 uL for a 384-well plate black wall/clear bottom plate.
- For non-adherent cells: Centrifuge the cells from the culture medium and then suspend the cell pellet in culture medium at 80,000 to 200,000 cells/well/90 uL for a 96-well or 20,000 to 50,000 cells/well/20 uL for a 384-well black wall/clear bottom plate. Centrifuge the plate at 800 rpm for 2 minutes with brake off prior to the experiments. Note: Each cell line should be evaluated on an individual basis to determine the optimal cell density for apoptosis induction
Sample Protocol:
- Treat cells by adding 10 µL/well of 10X test compounds (96-well plate) or 5 µL/well of 5X test compounds (384-well plate) into PBS or the desired buffer. For blank wells (medium without the cells), add the same amount of compound buffer.
- Incubate the cell plate in a 37°C, 5% CO2, incubator for a desired period of time (3 - 4 hours for Jurkat cells treated with staurosporine) to induce apoptosis.
- Add 100 µL/well/96-well or 25 µL/well/384-well plate of Caspase 3/7 Substrate working solution.
- Incubate the plate at room temperature for at least 1 hour, protected from light. Note: If desired, add 1 µL of the 1 mM Ac-DEVD-CHO caspase 3/7 inhibitor to selected samples 10 minutes before adding Caspase 3/7 working solution at room temperature to confirm the inhibition of the caspase 3/7-like activities.
- Monitor the fluorescence intensity with a fluorescence microplate reader (top or bottom read mode) at Ex/Em = 540/620 nm (Cutoff = 610 nm). Note: Sometimes, bottom read gives better signal to background ratio. Centrifuge cell plate (especially for the non-adherent cells) at 800 rpm for 2 minutes (brake off) if using bottom read mode.

Figure 1. Detection of Caspase 3/7 Activities in Jurkat cells. Jurkat cells were seeded on the same day at 200,000 cells/90 µL/well in a Costar black wall/clear bottom 96-well plate. The cells were treated with or without 1 µM of staurosporine for 5 hours. The caspase 3/7 working solution (100 µL/well) was added and incubated at room temperature for 1 hour. The fluorescence intensity was measured at Ex/Em = 540/620 nm (Cutoff = 610 nm) with FlexStation fluorescence microplate reader (Molecular Devices).
