Abstract
In situ hybridization (ISH) has become a standard method for the localization of nucleic acid sequences in chromosomes, single cells, and tissue sections. Nonradioactive ISH has not only eliminated the problems associated with radioactive probes but has also achieved a higher degree of resolution. Advances in probe preparation and labeling methods have facilitated the general application of ISH. In combination with immunohistochemistry, ISH can provide histological information on gene activity at the DNA, mRNA, and protein levels. Some nonradioactive ISH can simultaneously detect nucleic acid sequences in the same tissue or in a chromosome spread. Advances in ISH technology, including use of the polymerase chain reaction offer both a high sensitivity allowing detection of low levels of gene expression and the cytological localization of gene sequences.
