Cysteine-containing aspartate proteolytic enzymes (Caspase) are a family of cysteine proteases that play important roles in apoptosis, necrosis, and inflammation. Caspase-9 is a priming type of caspase that initiates endogenous apoptosis, which is apoptosis of the mitochondrial pathway. When cells are stressed, Cytochrome c is released into the cytoplasm and binds to the apoptotic protein activator 1 (Apaf-1) to form a complex. Caspase-9 was then recruited into this complex, forming the apoptotic bodies. In apoptotic bodies, caspase-9 is activated by self-cleavage. Activated caspase-9 further activates downstream effector caspases, such as caspase-3 and caspase-7.
Caspase-9 Fluorometric Assay Kit provides a convenient and simple way for detecting the LEHD-dependent caspase activity. LEHD-AFC (AFC:7-amino-4-trifluoromethyl coumarin) emits blue light (λmax = 400 nm); while cleavage of LEHD-AFC by Caspase-9 or related caspases, free AFC emits a yellow-green fluorescence (λmax = 505 nm), which can be quantified by using a microplate reader or a fluorometer. Comparison of the fluorescence of AFC from an apoptotic sample with an uninduced control determines the fold increase in Caspase-9 activity.
