  2. Fluorescence in situ hybridization - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_in_situ...

    A metaphase cell positive for the bcr/abl rearrangement (associated with chronic myelogenous leukemia) using FISH. The chromosomes can be seen in blue. The chromosome that is labeled with green and red spots (upper left) is the one where the rearrangement is present. Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique ...

  3. Q-FISH - Wikipedia

    en.wikipedia.org/wiki/Q-FISH

    Q-FISH. 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 ...

  4. Riboprobe - Wikipedia

    en.wikipedia.org/wiki/Riboprobe

    Fluorescence in situ hybridization (FISH)is the most widely used riboprobe technique. A target sequence and a probe are essential in FISH. First, the probe is labeled with either direct or indirect labeling strategy: hapten-modified nucleotides are used in indirect labeling, and fluorophore-modified nucleotides are used in direct labeling.

  5. Flow-FISH - Wikipedia

    en.wikipedia.org/wiki/Flow-FISH

    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. [1] [2] [3]

  6. Cytogenetics - Wikipedia

    en.wikipedia.org/wiki/Cytogenetics

    While radioisotope-labeled probes had been hybridized with DNA since 1969, movement was now made in using fluorescent-labeled probes. Hybridizing them to chromosomal preparations using existing techniques came to be known as fluorescence in situ hybridization (FISH). [22]

  7. In situ hybridization - Wikipedia

    en.wikipedia.org/wiki/In_situ_hybridization

    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 (in situ) or if the tissue is small enough (e.g., plant seeds, Drosophila embryos), in the entire tissue (whole mount ISH ...
