Apoptotic nuclear DNA fragmentation, a classic sign of apoptosis, is easily measured on a Guava System to identify apoptotic and non-apoptotic cell populations. The assay is simple. After staining cells with optimized reagents from the Guava TUNEL Reagent Kit, users have only to load samples onto a Guava System. The user-friendly Guava® TUNEL Software Module conveniently automates data acquisition, analysis, and storage, making the assay accessible to anyone in your lab, at any time.
