NOTE: Precipitation may occur when reagents are stored at −20°C. Warm reagents to 37°C if necessary to dissolve precipitate.
NOTE: Cell lysate plate can be stored at −80°C for future use.
NOTE: We recommend reading the plate immediately and recording RFU reading at time 0 hr. This will help determine if there is significant change in RFU at the end of incubation.
NOTE: This protocol has been tested in 384-well plate format, please adjust the volume proportionally based on the plate capacity. For example, if using 384-low volume plate, use 20 µl substrate solution B and 2.5 µl lysate.
NOTE: We recommend reading plates after 1 hr incubation. If the signal is too weak, increase incubation period to observe significant change in signal strength. If significant increase is signal strength is not observed, more lysate may be necessary.

All Species Expected
Caspase-3 (CPP-32, Apopain, Yama, SCA-1) is a critical executioner of apoptosis, as it is either partially or totally responsible for the proteolytic cleavage of many key proteins, such as the nuclear enzyme poly (ADP-ribose) polymerase (PARP) (1). Activation of caspase-3 requires proteolytic processing of its inactive zymogen into activated p17 and p12 fragments. Cleavage of caspase-3 requires the aspartic acid residue at the P1 position (2).
Caspase-7 (CMH-1, Mch3, ICE-LAP3) has been identified as a major contributor to the execution of apoptosis (3-6). Caspase-7, like caspase-3, is an effector caspase that is responsible for cleaving downstream substrates, such as PARP (3,5). During apoptosis, caspase-7 is activated by upstream caspases through proteolytic processsing at Asp23, Asp198, and Asp206, thereby producing the mature subunits (3,5). Similar to caspases-2 and -3, caspase-7 preferentially cleaves substrates following the recognition sequence DEVD (7).
