Fluorescence in situ hybridisation (FISH) is a rapid and reliable technique for chromosomal investigations that is used for a wide variety of cytogenetic purposes at present. This molecular-cytogenetic method has been developed continuously for many years. As a consequence, various modifications with different kinds of fluorescently labelled probes have been introduced to optimise the detection of DNA and RNA sequences. This review articlepaper presents the general principles of in situ hybridisation, probe labelling and examples of proper use of different kinds of probes. In addition, some newer FISH methods and their usefulness in human molecular cytogenetics are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
