Guava® TUNEL Kit

Optimized for ease of use and deeper, faster scientific insights


The Guava® TUNEL Kit – 100 Tests (Part Number: 4500-0121) detects apoptosis-induced DNA fragmentation through a quantitative fluorescence assay. Terminal deoxynucleotidyl transferase (TdT) catalyzes the incorporation of bromo-deoxyuridine (BrdU) residues into the fragmenting nuclear DNA at the 3′-hydroxyl ends by nicked-end labeling. A TRITC-conjugated anti-BrdU antibody can then label the 3′-hydroxyl ends for detection by a Guava System.


One of the hallmarks of late stage apoptosis, or programmed cell death, is the fragmentation of nuclear chromatin. As a result, the Guava TUNEL Kit can be used for detection of late-stage apoptosis.
