The overall goal of this experiment is to detect and track non-apoptotic caspase activity in live animals using Drosophila Melanogaster as a model. Caspases are proteases that cleave many cellular components to cause apoptotic cell death. Therefor

To detect healthy cells in whole animals that contain low levels of caspase activity, the highly sensitive biosensor designated CaspaseTracker was generated for Drosophila. Caspase-dependent biosensor activity is detected in long-lived healthy cells throughout the internal organs of adult animals reared under optimized conditions in the absence of death stimuli.
