One of the most valuable tools that have been developed for the study of apoptosis is the availability of recombinant active caspases. The determination of caspase substrate preference, the design of sensitive substrates and potent inhibitors, the resolution of caspase structures, the elucidation of their activation mechanisms, and the identification of their substrates were made possible by the availability of sufficient amounts of enzymatically pure caspases. The current chapter describes at length the expression, purification, and basic enzymatic characterization of apoptotic caspases.
