title: RNA FISH on Cultured Cells in Interphase.
abstract: INTRODUCTIONFluorescence in situ hybridization (FISH) has become a widely used method in genome and molecular genetic studies. The technique is highly versatile and has been adapted to carry out genome-wide screenings, microarray quantifications, cancer cytogenetics analysis, and RNA expression and localization studies. The study of intracellular RNA localization using RNA FISH provides insights into the in situ physical characteristics of transcription and intracellular RNA transport in individual cells. In our lab, we use RNA FISH to detect the localization of Xist RNA, a nuclear noncoding transcript that coats the entire chromosome from which it is transcribed. The advantage of using RNA FISH in our case is to extract precise molecular information directly in the context of cellular structure. The RNA FISH technique requires the generation of a labeled probe, hybridization of the probe to a fixed sample, and detection of the labeled probe using microscopy.
