Caspase-1 Colorimetric Assay Kit
Cysteine-dependent aspartate-directed proteases (Caspases) are a family of cysteine proteases that play important roles in apoptosis, necrosis, and inflammation. Sequential activation of caspases plays an important role in cell apoptosis. Caspase-1, also known as IL-1β-converting enzyme (ICE), is a key regulator of innate immunity. The active Caspase-1 cleaves and activates pro-inflammatory IL-1β and IL-18, and promotes an inflammatory form of cell death induced by apoptosis and pyroptosis.
Caspase-1 Colorimetric Assay Kit provides a convenient and simple way for detecting the YVAD-dependent caspase activity. When cleavage of YVAD from the labeled substrate YVAD-p-nitroaniline (YVAD-pNA) by Caspase-1 or related caspases, the free pNA light emission can be quantified by using a microplate reader or a spectrophotometer at 405 nm or 400 nm. Comparison of the absorbance of free pNA from an apoptotic sample with an uninduced control determines the fold increase in Caspase-1 activity.
Simple one-step procedure; takes 1-2 hours
Fast and convenient
Comparison of the absorbance of pNA from a treated sample with an untreated control allows determination of the fold increase in Caspase-1 activity.
