In situ hybridisation.
In situ hybridisation of mRNA in tissues or cell preparations is a powerful technique for studying gene expression. When combined with cell phenotyping with monoclonal antibodies it gives insights into the cellular basis of disease in vivo. The technique has also been used widely to identify foreign nucleic acids--for example, bacterial or viral, in host cells. The major disadvantages of this approach in the past have been that it was technically demanding, time consuming, and provided qualitative rather than quantitative results. Now, with the use of non-radioactive probes and improved imaging systems, the full potential of this form of molecular analysis is increasingly accessible and should generate rapid advances in many fields.
