Detection principle

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.

Answered: this kit can detect animal paraffin section, frozen section, cell slide. But insect sample is not verified in our lab. If you need to use insect samples for testing with this kit, I suggest to conduct pre-experiment to exploreteh sample preparation after consulting articles.
