In fluorescent "in situ" hybridization refers to the cellular placement of the probe Probe size is important because shorter probes hybridize less specifically than longer probes, so that long enough strands of DNA or RNA (often 10–25 nucleotides) which are complementary to a given target sequence are often used to locate a target.
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 ...
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 ...
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.

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 ...
Quantitative Fluorescent in situ hybridization (Q-FISH) is a cytogenetic technique based on the traditional FISH methodology. In Q-FISH, the technique uses labelled (Cy3 or FITC) synthetic DNA mimics called peptide nucleic acid (PNA) oligonucleotides to quantify target sequences in chromosomal DNA using fluorescent microscopy and analysis software.
For example, research by the Royal Veterinary College revealed that many British owners who acquired a puppy during the height of the Covid pandemic were struggling with their pet's behavior as ...
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).
