Single stranded DNA sequences, double stranded DNA sequences, single stranded RNA sequences or synthetic oligonucleotide sequences are used as probes during hybridization technique, and these probes are labeled with a radioactive phosphorus at its 5’ end for identification procedures upon autoradiography or labeled using fluorescent dyes.
There are different types of ISH techniques available based upon the type of probe used and the type of visualization technique followed.
There are many applications of ISH, mainly in the molecular diagnostics of infectious diseases in order to identify the presence of pathogens and to confirm the pathogen via molecular diagnostics.
It is also used in the fields of developmental biology, karyotyping and phylogenetic analysis and physical mapping of chromosomes.
Even in the case of the lightest elements where the ratio of neutron number to atomic number varies the most between isotopes it usually has only a small effect, although it does matter in some circumstances (for hydrogen, the lightest element, the isotope effect is large enough to strongly affect biology).The technique is based on antigen-antibody binding, and enzyme labels are used for this technique; one such application is the ELISA (Enzyme linked immunosorbent assay).The markers can also be fluorescent tagged antibodies or radio labeled antibodies. The diagnostic procedures target the antigens present on the tumor cells to identify and characterize the tumor. “FISH (Fluorescent In Situ Hybridization)” By Mr Matze – Own work (CC BY-SA 3.0) via Commons Wikimedia 2. From left to right, the isotopes are protium ( Isotopes are variants of a particular chemical element which differ in neutron number. The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of neutrons.
