Further details regarding sample type: Cell culture |
Protocol |
1. Induce apoptosis in cells by desired method. Concurrently incubate a control culture without induction. 2. Count cells and pellet 1-5 x 106 cells. 3. Resuspend cells in 50 μL of chilled Cell Lysis Buffer and incubate cells on ice for 10 minutes. Centrifuge for 1 min in a microcentrifuge (10,000 x g). 5. Transfer supernatant to a fresh tube and assay protein Concentration. 6. Dilute 100-300 μg protein to 50 μL Cell Lysis Buffer for each assay. 7. Add 50 μL of 2X Reaction Buffer containing 10 mM DTT to each sample. 8. Add 5 μL of the 4 mM pNA conjugated substrates (200 μ M final conc.) into each tube individually and incubate at 37 °C for 1-2 hour. 9 Read samples at 400- or 405-nm in a microtiter plate reader, or spectrophotometer using a 100- μL micro quartz cuvet (Sigma), or dilute sample to 1 mL with Dilution Buffer and using regular cuvet (note: Dilution of the samples proportionally decreases the reading). Fold-increase in caspase activity can be determined by comparing these results with the level of the uninduced control. Note: Background reading from cell lysates and buffers should be subtracted from the readings of both induced and the uninduced samples before calculating fold increase in caspase activity. |
