title: Rat karyotyping by fluorescence in situ hybridization (FISH): localization of oncogene c-raf to 4q42, retinoblastoma antioncogene to 15q12, and mitochondrial D-loop-like sequences to the Y chromosome.
abstract: Fluorescence in situ hybridization (FISH) has been used to karyotype the rat genome with long interspersed repetitive elements (LINEs). Two-color FISH experiments were used to localize the rat c-raf oncogene to 4q42 and the rat retinoblastoma anti-oncogene to 15q12. In addition, sequences similar to the rat mitochondrial origin of replication (D-loop-like sequences) have been found to be concentrated among repetitive element sequences on the Y chromosome. This report extends hybridization-based karyotype technology to the rat, thus facilitating the application of FISH to rat gene mapping.
