PG - 251-257 LID - 10.1007/978-1-0716-1158-6_15 [doi] AB - Immunofluorescence and fluorescence in situ hybridization (FISH) are widely used cytogenetic techniques for visualization of protein and RNA/DNA molecules. Here, we describe an experimental procedure for quick sequential immunofluorescence and RNA FISH (immuno-FISH), which enables the simultaneous detection of proteins, chromatin modifications, and RNAs on the inactive X-chromosome (Xi) using female mouse embryonic fibroblast (MEF) and tail-tip 3T3 cell lines. Using a pooled array of oligonucleotides labeled with a single fluorophore as an RNA FISH probe, we can reduce the time for RNA FISH from an overnight process to 1-2 h without losing its sensitivity. This protocol could be applied to visualization of various protein and RNA molecules, and chromatin modifications.
