Abstract
DNA fiber-FISH is an easy and simple light microscopic method to map unique and repeat sequences relative to each other at the molecular scale. A standard fluorescence microscope and a DNA labeling kit are sufficient to visualize DNA sequences from any tissue or organ. Despite the enormous progress of high-throughput sequencing technologies, DNA fiber-FISH remains a unique and indispensable tool to detect chromosomal rearrangements and to demonstrate differences between related species at high resolution. We discuss standard and alternative steps to easily prepare extended DNA fibers for high-resolution FISH map**.
