A protocol for comparative genomic hybridization by use of nucleotides directly labeled with fluorochromes was used to map regions of deletion and amplification in ten glioma cell lines. The protocol greatly reduced experimental artifacts. We detected several genetic aberrations, including whole chromosome loss and gain, partial loss and gain, possible isochromosome, and higher level DNA amplification. The most frequent losses (in order of frequency) occurred on chromosomes 10, 18, 13, 11, 9, 14, 4, 6, 1, and X. The most common gain occurred on chromosome 7. Several sites of previously known and unknown amplifications were observed.
