Abstract

A significant improvement in fluorescence in situ hybridization, enabling the detection of single-copy genes as small as 500 bp directly on banded chromosomes, is presented. The induction of chromosome banding, which does not require additional handling or any system of amplification, is obtained simply by using an alkaline (pH 11) p-phenylenediamine anti-fade solution. As the banding produced is related to the timing of 5-bromodeoxyuridine incorporation, either R- or G-banding, constitutive heterochromatin staining, or chromosome asymmetry can be observed simultaneously with the fluorescent hybridized spots. Results of hybridization of small cDNA probes for the human genes for motilin, thymidylate synthetase, and lymphocyte activation-3 are provided as examples of the high-resolution mapping obtainable with this technique.
