Abstract
Individual chromosomes can be identified by means of in situ hybridization with DNA probes for chromosome-specific repetitive sequences. The efficiency and sensitivity of the method are strictly dependent on the characteristics of the probes and the experimental conditions. Using three probes with different copy numbers, we demonstrated that the target chromosomes can be visualized in interphase when the homologous sequences are repeated at least 50 times. Possible applications of interphase analysis to clinical cytogenetics and mutagenicity testing are discussed.Keywords
