When cells undergo apoptosis, specific DNA endonucleases will be activated, cutting the genomic DNA between the nucleosomes. The DNA of apoptotic cells is cleaved into multimers of 180~200bp fragments, corresponding to the oligonucleosomal size. Therefore, the DNA of apoptotic cells typically migrates as a ladder of 180~200bp on an agarose gel. The exposed 3'-OH of the broken DNA can be catalyzed by Terminal Deoxynucleotidyl Transferase (TdT) with fluorescein labeled dUTP, which can be detected with fluorescence microscope.

Paraffin embedded rat heart was treated with DNase I to fragment the DNA. DNA strand breaks showed intense fluorescent staining in DNase I treated sample (green). The cells were counterstained with DAPI (blue). This photo was taken by confocal microscope. Paraffin embedded rat heart was treated with DNase I to fragment the DNA.
