Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique that uses fluorescent probes that bind to only particular parts of a nucleic acid sequence with a high degree of sequence complementarity.
In situ hybridization (ISH) is a type of hybridization that uses a labeled complementary DNA, RNA or modified nucleic acid strand (i.e., a probe) to localize a specific DNA or RNA sequence in a portion or section of tissue or if the tissue is small enough (e.g., plant seeds, Drosophila embryos), in the entire tissue (whole mount ISH), in cells ...
The three basic varieties of physical mapping are fluorescent in situ hybridization (FISH), restriction site mapping and sequencing by clones. [ 5 ] The goal of physical mapping, as a common mechanism under genomic analysis, is to obtain a complete genome sequence in order to deduce any association between the target DNA sequence and phenotypic ...
Flow-FISH (fluorescence in-situ hybridization) is a cytogenetic technique to quantify the copy number of RNA or specific repetitive elements in genomic DNA of whole cell populations via the combination of flow cytometry with cytogenetic fluorescent in situ hybridization staining protocols.

Fluorescence in situ hybridization (FISH) is a laboratory method used to detect and locate a DNA sequence, often on a particular chromosome. [4]In the 1960s, researchers Joseph Gall and Mary Lou Pardue found that molecular hybridization could be used to identify the position of DNA sequences in situ (i.e., in their natural positions within a chromosome).
Fluorescence in situ hybridization (FISH) refers to using fluorescently labeled probe to hybridize to cytogenetic cell preparations. In addition to standard preparations FISH can also be performed on: bone marrow smears; blood smears; paraffin embedded tissue preparations; enzymatically dissociated tissue samples; uncultured bone marrow ...
Fluorescence in situ hybridization (FISH), is an example of a genetic labeling technique that utilizes probes that are specific for chromosomal sites along the length of a chromosome, also known as chromosome painting. Multiple fluorescent dyes that each have a distinct excitation and emission wavelength are bound to a probe which is then ...
