IN SITU HYBRIDIZATIONS Meaning and
Definition
-
In Situ Hybridization (ISH) is a technique used in molecular biology and genetics to visualize the localization of specific nucleic acid sequences within cells or tissues. It allows researchers to examine the spatial distribution of RNA or DNA molecules in their original context, providing insight into gene expression patterns and understanding developmental processes.
The procedure involves the use of a labeled probe, which is a complementary sequence to the target nucleic acid sequence of interest. The probe is usually tagged with either a fluorescent dye or a radioisotope for detection purposes. The labeled probe is then applied to the sample, allowing it to hybridize with the complementary target sequence present in the cells or tissue sections.
After hybridization, any unbound probe is washed away, and the labeled complex formed between the probe and target sequence is visualized using appropriate detection methods. Fluorescence in situ hybridization (FISH) uses fluorescence microscopy to detect the fluorescently labeled probes, while autoradiography or scintillation counting is used for radioactively labeled probes.
In Situ Hybridization provides information about gene expression patterns, as well as the cellular and subcellular localization of specific genetic elements within tissues. It has a wide range of applications in various fields, including developmental biology, pathology, cancer research, and neurobiology. This technique has revolutionized the understanding of gene regulation, pathogenic mechanisms, and the identification of molecular markers in cellular and developmental processes.
