Product Description

Each control slide contains formalin fixed, paraffin-embedded Jurkat cells, both untreated and treated with etoposide, that serve as a control for cleaved caspase-3 (Asp 175) immunostaining. Western blot analysis was performed on extracts derived from the same cells to verify the efficacy of the etoposide treatment.

To be used with antibodies: 9664, 9661, 9662, 2035, 9541.


Caspase-3 (CPP-32, Apoptain, 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).
