Demonstration of active caspases in apoptotic cells by immunofluorescence using FAM-FLICA apoptosis detection kits.Both cells are apoptotic and dying expressing various active caspases (green). Nuclei are counterstained blue.
Both cells are apoptotic (green) and dying (blue nuclei). As the left cell is much brighter green than the right cell, the left cell had more active caspases.
