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 ...

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]
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 ...
Spatial transcriptomics is a method that captures positional context of transcriptional activity within intact tissue [1].The historical precursor to spatial transcriptomics is in situ hybridization [2], where the modernized omics terminology refers to the measurement of all the mRNA in a cell rather than select RNA targets.
Chromogenic in situ hybridization (CISH) is a cytogenetic technique that combines the chromogenic signal detection method of immunohistochemistry (IHC) techniques with in situ hybridization. [ 1 ] [ 2 ] It was developed around the year 2000 as an alternative to fluorescence in situ hybridization (FISH) for detection of HER-2/neu oncogene ...
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.
The key adaptation to the base protocol was the removal of the SDS solubilization step after digestion to preserve nuclear structure and prevent random ligation between fragmented chromatin by ligation within the intact nuclei, which formed the basis of in situ Hi-C. [12] In 2021, Hi-C 3.0 was described by Lafontaine et al., with higher ...
