Used to detect DNA fragmentation in apoptotic cells, this assay is widely applied in cancer research, toxicology, and developmental biology. The fluorescence signal at 555 nm allows for clear visualization under a fluorescence microscope, making it ideal for identifying programmed cell death in tissue sections, cell cultures, and fixed samples. It is commonly used to evaluate the effectiveness of chemotherapeutic agents, study neurodegenerative diseases, and assess cellular responses to environmental stressors. The kit enables sensitive and specific detection, compatible with flow cytometry and high-content screening platforms.
