Term Name:	terminal deoxynucleotidyl transferase dUTP nick end labeling assay evidence
Synonyms:	TdT-mediated dUTP-biotin nick end labeling assay, terminal deoxynucleotidyl transferase-dUTP nick end labeling assay evidence, TUNEL assay evidence
Definition:	A type of apoptotic assay evidence resulting from the visualization of DNA fragmentation by detection of exposed 3'-OH ends, localized by terminal deoxynucleotidyl transferase (TdT) which then catalyzes the addition of labeled dUTPs.
