      Description
      OverviewA fast, convenient, and sensitive method to measure caspase-8 in living cells. The fluorescent marker, FITC-IETD-FMK, is a labeled, cell-permeable, non-toxic inhibitor that binds irreversibly to activated caspase-8 in living cells. Caspase-8 can be detected by the measurement of fluorescence in a fluorescent microplate reader, flow cytometer, or by fluorescence microscopy.

      Principles of the assayThis Calbiochem® brand Caspase-8 Detection Kit provides a convenient and sensitive means for detecting activated caspase-8 in living cells. The assay employs a Caspase-8 inhibitor conjugated to FITC, the fluorescent marker FITC-IETD-FMK, is a cell-permeable, non-toxic inhibitor that binds irreversibly to activated caspase-8 and allows the detection of Caspase-8 by the measurement of fluorescence intensity (excitation max.: ~485 nm; emission max.: ~535 nm) in a fluorescent microplate reader, by flow cytometry, or by fluorescence microscopy.

      Detailed protocolCaspase-8 Assay Procedures

      Staining

      1. Induce apoptosis in cells (1 x 106/ml) as desired. Concurrently incubate a control culture without apoptosis induction. An additional negative control can be prepared by adding the caspase inhibitor Z-VAD-FMK at 1 µl/ml to an induced culture to inhibit caspase activity.
      2. Aliquot 300 µl each of the induced and control cultures into eppendorf tubes.
      3. Add 1 µl of FITC-IETD-FMK to each tube and incubate for 0.5-1 h in a 37°C incubator with 5% CO2.
      4. Centrifuge cells at 3,000 rpm for 5 min and remove the supernatant.
      5. Resuspend cells in 0.5 ml of wash buffer and centrifuge again at 3000 rpm for 5 min.
      6. Repeat step 5.

      Proceed depending on method of analysis.

      Quantification by Flow Cytometry

      1. For flow cytometric analysis, resuspend cells in 300 µl of wash buffer and place on ice.
      2. Analyze samples by flow cytometry using the FL-1 channel.

      Detection by Fluorescence Microscopy

      1. Resuspend cells in 100 µl of wash buffer.
      2. Add one drop of the cell suspension to a microslide and cover with a coverslip.
      3. Observe cells under a fluorescence microscope using a FITC filter. Caspase-8 positive cells appear to have brighter green signals, whereas caspase-8 negative control cells show a weaker signal.

      Analysis by Fluorescence Plate Reader

      1. Resuspend cells in 100 µl of wash buffer.
      2. Transfer the cell suspension to each well of the black plate.
      3. Measure the fluorescence intensity at Ex. max. 485 nm and Em. max. 535 nm. For control, use wells containing unlabeled cells.
