Advances in fluorescence in situ hybridization.

The techniques of in situ hybridization (ISH) are widely applied for analyzing the genetic make-up and RNA expression patterns of individual cells. This review focusses on a number of advances made over the last 5 years in the fluorescence ISH (FISH) field, i.e., Fiber-FISH, Multi-colour chromosome painting, Comparative Genomic Hybridization, Tyramide Signal Amplification and FISH with Polypeptide Nucleic Acid and Padlock probes.
