An oligonucleotide with an abasic site analog at position 28 generates a different DNA cleavage pattern than does OTI28. Lanes 1–3 contain a radiolabeled unmodified PML top/target strand hybridized to an unmodified PML bottom strand in the absence of enzyme, or in the presence of enzyme and 0–500 μM free etoposide. Lanes 4 and 5 contain a radiolabeled PML top strand hybridized with OTI28 (bottom strand). Lanes 6 and 7 contain a radiolabeled unmodified PML top strand hybridized to a bottom strand oligonucleotide containing an abasic site analog at position 28 (AP28). Lane 8 contains reference (R) oligonucleotides that are 24, 23 and 19 bases in length. The gel is representative of at least three independent experiments.
