Description

The polyclonal antibody reacts with Caspase-3 (also known as CPP32); the antibody was, raised against a peptide mapping to the amino terminus of human caspase-3 precursor. Caspases are a family of mammalian proteases that regulate many of the morphological and biochemical features of apoptosis. The currently identified caspases can be divided into three groups: apoptotic initiators, apoptotic executioners, and inflammatory mediators (1,2). Caspase-2, 8, and 9 have been identified as apoptotic initiators (3,4). Caspase-2 (also designated Nedd-2/ICH-1) can be alternatively spliced to produce two distinct Caspase-2 mRNA species. One mRNA species encodes a protein of 435 amino acids in length and the mRNA splice variant encodes a 312 amino acid protein. The larger protein, Caspase-2L, in an over expressed state, leads to programmed cell death. Conversely the over expression of Caspase-2S protein, a truncated version of Caspase-2L, has been shown to suppress cell death induced by serum deprivation (5). The executioner caspases include caspase-3, 6 and 7. Of these three proteases Caspase-3 is considered to be the essential for the chromatin margination, DNA fragmentation, and nuclear collapse during apoptosis (6). Caspase-1 (also known as ICE) is considered to be a mediator of the inflammatory response by converting the inactive precursor of interleukin-1b to the 17 kDa proinflammatory cytokine, IL-1b (7,8).
