Visualize Caspase-3 Activity in Real Time

Magic Red™ Caspase-3/7 detection assays measure apoptosis-associated DEVDase enzyme activity in living, intact cells.

The fluorogenic Magic Red™ Caspase-3/7 detection reagent consists of two caspase-3/7 target sequences and the dye cresyl violet. When the cresyl violet molecule (Magic Red™) is di-substituted with two DEVD peptide sequences, the cell-permeant reagent is essentially non-fluorescent. The presence of the active forms of DEVD-ase enzymes caspases 3 and 7, found in apoptotic cells, causes the hydrolysis of the two DEVD target sequences from the Magic Red™ fluorophore, converting it to the fluorescent form. As apoptosis progresses and caspase-3/7 activity increases, the red fluorescent signal increases. Magic Red™ (cresyl violet) excites at 540-590 nm (590 nm optimal) and emits at >610nm (630 nm optimal).
