FISH with Whole Chromosome Painting Probes

Abstract

Some types of chromosome aberrations are not easily identified by the traditional Giemsa staining. It usually needs some banding technique and skilled person's eye. Whole chromosome painting FISH probe can stain designated entire chromosomes or domains in metaphase chromosomes or interphase nuclei, respectively. It allows to visually identify translocations, deletions, or amplifications of specific chromosomes. Once chromosomes are stained, even non-skilled researchers can easily identify those chromosome aberrations. Whole chromosome painting FISH has higher sensitivity to detect chromosome aberrations. This chapter introduces the method for whole chromosome painting FISH staining.
