PG - 881-90 AB - A significant part of the eukaryotic genomes consists of repetitive DNA, which can form large clusters or distributed along euchromatic chromosome regions. Repeats located in chromosomal regions make a problem in analysis and identification of the chromosomal material with fluorescence in situ hybridization (FISH). In most cases, the identification of chromosome regions using FISH requires detection of the signal produced with unique sequences. The feasibility, advantages and disadvantages of traditional methods of suppression of repetitive DNA hybridization, methods of repeats-free probe construction and methods of chromosome-specific DNA sequences visualization using image processing of multicolor FISH results are considered in the paper. The efficiency of different techniques for DNA probe generation, different FISH protocols, and image processing of obtained microscopic images depends on the genomic size and structure of analyzing species. This problem was discussed and different approaches were considered for the analysis of the species with very large genome, rare species and species which specimens are too small in size to obtain the amount of genomic and Cot-1 DNA required for suppression of repetitive DNA hybridization.
