Abstract

We investigated if any change in spatial resolution of comparative genomic hybridization analysis could be detected when using DNA amplified by degenerate oligonucleotide primed PCR (DOP-PCR) as opposed to the use of unamplified DNA. Five DNA samples from B-cell leukemias with small 11q deletions were amplified by DOP-PCR and analysed by means of high resolution comparative genomic hybridization (HR-CGH) for the evaluation of aberration size detection limit. By means of HR-CGH, we found the detection limit of DOP-PCR CGH for deletions to be between 3 Mbp and 7-8 Mbp.
