In Situ Hybridization

In Situ Hybridization In situ hybridization (ISH) is a type of histochemical application that capitalizes on sequence-specific DNA or RNA binding. With the use of labeled, complementary DNA and RNA oligonucleotides, genomic regions and gene expression can be visualized within the context of cells and tissues. ISH is a well-established technique first introduced in the 1960s to localize the positions of specific DNA sites within a chromosome (Gall and Pardue). Various labels for ISH probes have been developed and used, including radioactive isotopes and dyes. Fluorescent in situ hybridization (FISH) makes use of fluorophores, while chromogenic in situ hybridization (CISH) uses probes labeled with biotin or digoxigenin. These variants of ISH are now widely used in studies in gene amplification, chromosomal analysis, mRNA expression, and microbial detection. This listing of in situ hybridization products aims to help researchers explore relevant tools, including hybridization probes, ISH kits, reagents, and more.
