Presence of double-strand breaks with single-base 3' overhangs in cells undergoing apoptosis but not necrosis


Apoptotic cells in rat thymus were labeled in situ in paraffin-embedded and frozen tissue sections by ligation of double-stranded DNA fragments containing digoxigenin or Texas red. Two forms of double-stranded DNA fragments were prepared using the polymerase chain reaction: one was synthesized using Taq polymerase, which yields products with single-base 3… (More)
