Product details
Calpain Activity Assay Kit ab65308 provides optimized buffers and reagents for a convenient measurement of calpain activity.
The extraction buffer included in the kit specifically extracts cytosolic proteins without contamination by cell membrane and lysosome proteases. It also prevents auto-activation of calpain during the extraction procedure. Thus, the kit detects only activated calpain within the cytosol.
The calpain activity assay protocol is based on the detection of cleavage of calpain substrate Ac-LLY-AFC. Ac-LLY-AFC emits blue light (λmax = 400 nm); upon cleavage of the substrate by calpain, free AFC emits a yellow-green fluorescence (λmax = 505 nm), which can be quantified using a fluorometer or a fluorecence plate reader. Comparison of the fluorescence intensity from a treated sample with a normal control allows determination of the changes in calpain activity.

Biological function summary
Calpain 1 participates in cellular functions such as signal transduction cell cycle progression and apoptosis. It is not part of a complex but operates independently to modulate cellular responses by processing different target proteins. Calpain protein activity impacts cytoskeletal remodeling and membrane repair important processes in cell mobility and stability. Through its proteolytic actions calpain 1 influences neural plasticity and muscle function demonstrating its broad biological significance.
Pathways
Calpain 1 functions within the calcium signaling and apoptotic pathways highlighting its role in regulating cellular survival and death. Calcium influx triggers calpain activity linking it to proteins such as calmodulin and calcineurin that also respond to calcium signals. Calpain-1 modulates apoptosis by targeting Bcl-2 family proteins influencing cell fate during stress responses. The calpain assay measures its activity providing insights into its contribution to these vital pathways.
