Apoptosis and Cytotoxicity
Z-DEVD-AMC is a fluorogenic 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 fluorescent 7-amido-4-methylcoumarin (AMC).

Protocol


Quick Preview

This protocol only provides a guideline, and should be modified according to your specific needs.

1.       General Solution Caspase Assays Using AMC, AFC, pNA, R110 and ProRed Substrates

1.1.     Prepare a 10 mM stock solution in DMSO.

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

50 µL substrate stock solution

100  µL DTT (1M)

400  µL EDTA (100 mM)

10 mL Tris Buffer (20 mM), pH =7.4

1.3.     Mix equal volume of the caspase standards or samples with 2X caspase substrate assay solution (from Step 1.2), and incubate the solutions at room temperature for at least 1 hour.

1.4.     Monitor the fluorescence using a fluorescence microplate reader, or absorbance using an absorbance microplate reader.

2.       Cell Caspase Assays Using Cell-Permeable FMK Caspase Probes

2.1.     Prepare a 2-5 mM stock solution in DMSO.

2.2.     Treat cells as desired.

2.3.     Prepare a 2X permeable caspase substrate (20 µM) assay solution by diluting the DMSO stock solution (from Step 2.1) in Hanks with 20 mM Hepes buffer (HHBS).

2.4.     Mix equal volume of the treated cells with 2X caspase substrate assay solution (from Step 2.3), and incubate the cells in a 37°C, 5% CO2 incubator for at least1 hour.

2.5.     Wash the cells with HHBS for at least once.

2.6.     Monitor the fluorescence intensity by a flow cytometer, a fluorescence microscope or a fluorescence microplate reader.

3.       Cell Caspase Assays Using Cell-Permeable FMK Caspase Probes (For #13470-13476 only)

3.1.     Prepare a 250X stock solution by adding 50 µL DMSO into the vial.

3.2.     Treat cells as desired.

3.3.     Add 250 X DMSO stock solution (from Step 3.1) into the cell solution at a 1:250 ratio (such as 2 uL to 500 uL cells), and incubate the cells in a 37°C, 5% CO2 incubator for 1 hour.

3.4.     Wash the cells with HHBS for at least once.

3.5.     Monitor the fluorescence intensity by flow cytometer, fluorescence microscopy or fluorescent microplate reader.
