title: The use of laser microdissection for the preparation of chromosome-specific painting probes in farm animals.
abstract: Laser microbeam microdissection and laser pressure catapulting procedure were used for the construction of chromosome-specific painting probes, arm-specific probes and probes for chromosomal subfragments. We report on a method for generation of fluorescence in-situ hybridization probes from laser dissected chromosomes of farm animals. So far, using the described method, a set of chromosome-specific painting probes has been obtained for all porcine chromosomes, 17 chromosomes of cattle and selected equine chromosomes. It is concluded that the laser technology appears to be a useful and powerful tool for the construction of chromosome-specifi c painting probes. Its main advantage is the fast non-contact collection of chromosomes.
