Analysis of telomere instability in MEFs deficient for DNA-PKcs and/or 53BP1 (<i>Prkdc</i>/<i>Trp53bp1</i> MEFs).

<p>Metaphases were stained with a telomere probe and scored for telomere fusions (TFs). TFs were further classified as “chromosome-type” or “chromatid-type”.</p><p>Analysis of telomere instability in MEFs deficient for DNA-PKcs and/or 53BP1 (<i>Prkdc</i>/<i>Trp53bp1</i> MEFs).
