Used for the quantitative measurement of active Caspase-3 in rat cell and tissue lysates. This kit is widely applied in apoptosis research, particularly in studies related to neurodegenerative diseases, cancer, and toxicology. It enables researchers to detect and monitor the activation of Caspase-3, a key executioner protease in the apoptotic pathway, providing insight into cell death mechanisms in experimental models. The assay is suitable for high-throughput screening and evaluation of therapeutic agents that modulate apoptosis.
