The RNA fluorescence in situ hybridization (RNA-FISH) methodology offers an attractive strategy to deepen our knowledge on the long noncoding RNA biology. In this chapter, we provide a comprehensive overview of the current RNA-FISH protocols available for imaging nuclear and cytoplasmic lncRNAs within cells or tissues. We describe a multicolor approach optimized for the simultaneous visualization of these transcripts with their specific molecular interactors, such as proteins or DNA sequences. Common challenges faced by this methodology such as cell-type specific permeabilization, target accessibility, image acquisition, and post-acquisition analyses are also discussed.
