Description
Overview

This product has been discontinued.





Specifically detects caspase-7 activity using the DEVD-AFC substrate. Caspase-7 substrates such as DEVD will also detect the activity of other caspases including caspase-3. This kit ensures specificity by first capturing caspase-7 using a selective antibody.

Intended useThe Calbiochem® Caspase-7 Immunoassay/Activity Kit is intended for the specific, semi-quantitative detection of caspase-7 activity.
Principles of the assayThe Calbiochem® Caspase-7 Immunoassay/Activity Kit utilizes a caspase-7 polyclonal antibody to capture activated caspase-7 from cell lysates. A fluorogenic substrate, DEVD-AFC, is then added to the wells and is cleaved by the captured, active caspase-7. The cleavage generates free AFC that is then analyzed using a fluorescence plate reader with an excitation wavelength of 370-425 nm and an emission wavelength of 490-525 nm. The increase in fluorescence is directly proportional to the caspase-7 activity.

Caspase-7 substrates such as DEVD will also be cleaved by other caspases, including caspase-3. However, by incorporating a specific capture step the assay only measures caspase-7 activity and other known caspases and non-specific proteases are not detected.

Materials Required but not provided• PBS
PreparationPreparation of Cell Lysates 1. Induce apoptosis as desired. Include a negative control using uninduced cells. Collect 5x106 cells per assay. 2. Wash cells with ice-cold PBS. Centrifuge at 700 x g. 3. Resuspend cells in 200 µl cold Cell Lysis Buffer. Incubate for 10 min on ice. 4. Centrifuge at 10,000 x g for 1 min. 5. Transfer the supernatant to a clean tube. Use immediately or aliquot and freeze (-20°C). The supernatant can be stored at -20°C for up to 6 months.
Reagent preparation•1X Anti-Caspase-7 Antibody: Prepare the desired amount of 1X Anti-Caspase-7 Antibody by making a 1:20 dilution of the Anti-Caspase-7 Antibody, 20X in Coating Buffer. •Recombinant Caspase-7: Reconstitute the Recombinant Caspase-7 in 10 µl PBS. Dilute 1:100 in Cell Lysis Buffer as needed for the assay.
Detailed protocol1. Add 100 µl 1X Anti-Caspase-7 Antibody to each well. Cover the plate tightly with an Adhesive Plate Cover and incubate at 37°C for 1 h or at 4°C overnight.
2. Remove the antibody solution from the wells.
3. Add 150 µl Blocking Buffer to each well. Cover the plate tightly with an Adhesive Plate Cover and incubate at room temperature for 30 min.
4. Remove the Blocking Buffer and wash the wells 3 times with 150 µl Incubation Buffer.
5. Add 100 µl cell lysate or 1 unit Recombinant Caspase-7 (positive control) to Anti-Caspase-7 Antibody-coated wells. Cover the plate tightly with an Adhesive Plate Cover and incubate at 37°C for 1 h.
6. Remove the solutions from the wells and wash 3 times with 150 µl Incubation Buffer.
7. Add 94 µl Incubation Buffer, 5 µl DEVD-AFC, and 1 µl DTT to each well. Cover the plate tightly with an Adhesive Plate Cover and incubate for 2-4 h at 37°C. Overnight incubation at 37°C may increase sensitivity.
8. Read the samples using a fluorescence plate reader set at an excitation wavelength of 370-425 nm and an emission wavelength of 490-525 nm. Determine the Caspase-7 activity by comparing results with the activity level of the uninduced control.
