Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation,

Specificity / Sensitivity

Caspase-5 (D3G4W) Rabbit mAb recognizes endogenous levels of total caspase-5 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro154 of human caspase-5 protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from THP-1 cells differentiated with TPA #4174 (80 nM, overnight) followed by treatment with LPS #14011 (1 μg/ml, indicated times), using Caspase-5 (D3G4W) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower)

Western Blotting

Western Blotting

Western blot analysis of extracts form 293T cells, mock transfected (-) or transfected with constructs expressing full-length human caspase-4 protein (hCasp4; +) or caspase-5 protein (hCasp5; +), using Caspase-5 (D3G4W) Rabbit mAb (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower).


Caspase-5 (Ich-3/ICErelIII/TY) is a member of the caspase family of cysteine proteases that play a key role in the execution of apoptosis and activation of inflammatory cytokines (1-3). Caspase-5 is widely expressed, with highest expression observed in placenta and lung (1). Interferon-γ and LPS regulate expression of caspase-5 (2,4). Members of the caspase-1 subfamily of caspases, which includes caspase-4, -5, and murine caspase-11 and -12, can induce apoptosis when over-expressed and mediate the proteolytic activation of inflammatory cytokines (5). Processing of IL-1β occurs through the activation of an inflammasome complex consisting of caspase-1, caspase-5, Pycard and NALP1 (6). Transcription factor Max, a component of the Myc/Mad/Max network, is cleaved by caspase-5 during Fas-induced apoptosis (7). Several alternative spliced variants of caspase-5 have been identified (8). Frameshift mutations of caspase-5 have been observed in leukemia, lymphoma (9), and colorectal cancers (10).
