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. Caspases activation is widely accepted as a reliable indicator for cell apoptosis. This particular kit is designed to simultaneously monitor four key caspases (caspase-3/7, 8 and 9) activation involved in cell apoptosis using three distinct fluorescent colors. This kit uses DEVD-ProRed™, IETD-R110 and LEHD-AMC as fluorogenic indicators for caspase 3/7, 8 and 9 activity respectively. Upon caspase cleavages, DEVD-ProRed™, IETD-R110 and LEHD-AMC caspase substrates generate three distinct fluorophores: ProRed™ (red fluorescence), R110 (green fluorescence) and AMC (blue fluorescence), which can be readily monitored in a single assay due to their nice spectral separation.

Protocol summary
- Prepare cells with test compounds
- Add equal volume of caspase working solution
- Incubate at room temperature for 30 min to 1 hour
- Monitor fluorescence intensity
Important notes
Thaw kit components at room temperature before use.
PREPARATION OF WORKING SOLUTION
1. Single caspase activity working solution
Make caspase 3/7, caspase 8 or caspase 9 working solution by adding 50 µL of substrate (Component A, B or C) into 10 mL of Assay Buffer (Component D), and mix them well.
2. Dual- or tri- caspase activity working solution:
Add 50 µL of each interested caspase substrate into 10 mL of Assay Buffer (Component D) together to make the working solution. Note: Please prepare the tested substrate solutions and the needed volume proportionally.

SAMPLE EXPERIMENTAL PROTOCOL
- Treat cells by adding 10 µL/well of 10X test compounds (96-well plate) or 5 µL/well of 5X test compounds (384-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 - 5 hours for Jurkat cells treated with staurosporine) to induce apoptosis.
- Add 100 µL/well/96-well or 25 µL/well/384-well plate of desired caspase assay working solution.
- Incubate the plate at room temperature for at least 30 to 60 min, protected from light. Note: If desired, add 1 µL of 1 mM caspase inhibitor to selected samples 10 minutes before adding the assay loading solution at room temperature to confirm the inhibition of caspase activities.
- Monitor the fluorescence intensity as indicated in the table with either top or bottom read mode. Note: Sometimes, bottom read gives better signal to background ratio, centrifuge cell plate (especially for the nonadherent cells) at 800 rpm for 2 minutes (brake off) if using bottom read mode.

Capase | Fluorescence | Excitation | Emission |
Caspase 3/7 | Red | 535 nm | 620 nm |
Caspase 8 | Green | 490 nm | 525 nm |
Caspase 9 | Blue | 370 nm | 450 nm |

Figure 1. Detection of Caspase Activities in Jurkat cells. Jurkat cells were seeded on the same day at 200,000 cells/well in a Costar black wall/clear bottom 96-well plate. The cells were treated with staurosporine at the final concentration of 1 mM for 4 hours (Red Bar) while the untreated cells were used as control (Blue Bar). The single-caspase assay loading solution (100 uL/well) was added (in #1 for caspase 3/7, #2 for caspase 8 or #3 for caspase 9) or Triple-caspase assay loading solution (#4 for caspase 3/7, 8 and 9 together) was added, and incubated at room temperature for 1 hour. The fluorescence intensity was measured with FlexStation fluorescence microplate reader at the indicated wavelength. The caspase 3/7, 8 and 9 activities can be detected in a single assay without interferences from other caspases.

Figure 2. cSBL induced apoptosis in H2452 and MSTO cells via activation of the caspase pathway. Caspase-3, -8, and -9 activation was detected by western blotting (A, B) or fluorometry (C, D). Fluorometry was performed independently three times and data are expressed as the mean ± SD. The statistical significance of these experiments compared with the control is shown in as follows: *P<0.05, **P<0.01, ***P<0.001.
