Storage
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.
Protocol
Specificity / Sensitivity
Caspase-4 (F4T9L) Rabbit mAb recognizes endogenous levels of total caspase-4 protein. This antibody detects processing intermediate forms of caspase-4 at 40 kDa and 32 kDa, as well as caspase-4 cleavage products at 25 kDa and 22 kDa.
Species Reactivity:
Human
Source / Purification
Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the p20 subunit of human caspase-4 protein.
Background
Caspase-4 (TX/ICH-2/ICErelII) is a member of the caspase family of proteases that play a key role in the execution of apoptosis and activation of inflammatory cytokines (1-3). Expression of caspase-4 has been observed in most tissues except brain, with highest levels in placenta, lung, spleen, and peripheral blood lymphocytes (PBL). Caspase-4 was originally found to contribute to Fas-mediated apoptosis (4). Several caspases (including caspase-4, caspase-5, and mouse caspase-11 and -12) are most closely related to caspase-1 and are capable of inducing apoptosis when overexpressed but are better characterized in the proteolytic activation of inflammatory cytokines (5). Caspase-4 associates with TRAF6 and is involved in the LPS inducible production of inflammatory cytokines IL-8 and MIP1 in THP-1 cells (6). While caspase-4 and mouse caspase-12 localize to the endoplasmic reticulum (ER) and may be activated by drugs that induce ER stress (7), at least one study suggests that caspase-4 and caspase-12 are not essential for ER stress-induced apoptosis (8).
