Kinetic Quantification of Caspase-3/7 Mediated Apoptosis Using Live-Cell Imaging

Apoptosis, the biological process by which cells undergo programmed cell death, is required for normal tissue maintenance and development. However, aberrations in apoptotic signaling networks are implicated in numerous human diseases including neurodegeneration and cancer. This poster describes a study where an assay system for studying apoptosis was optimized, incorporating a bi-functional reagent containing the DEVD motif linked to a DNA dye for use on the IncuCyte FLR imaging system. When added to cell culture growth medium, this relatively inert, non-fluorescent molecule crosses the cell membrane where it is available to be a substrate for activated caspase-3/7.
