Used in apoptosis research to quantify caspase-activated deoxyribonuclease (CAD) levels in cell lysates. Helps assess DNA fragmentation during programmed cell death. Commonly applied in studies of cancer, neurodegenerative diseases, and developmental biology. Enables researchers to evaluate the activation of apoptotic pathways in response to drugs or toxins. Suitable for high-throughput screening in pharmaceutical development. Provides a reliable, sensitive method to measure CAD activity without radioisotopes or gel electrophoresis.
