Technical fluorescence in situ hybridization (Fluorescence in situ hybridization - FISH) is a technique of hybridization probes (DNA sequences) with fluorophores attached to DNA on the chromosome landing BN as dividing cells ( metaphase) or division (interphase). DNA fragments are fixed after landing on the surface of the template, denaturation, and hybridization in conditions suitable for DNA fragment attached fluorophores forming DNA double helix chain. After hybridization, the template is quick rinse to remove the piece of DNA pairing nonspecific fixed and colored with DAPI II counterstained solution. Results were analyzed under fluorescent microscope to detect abnormalities on chromosomes and the genes involved. ...
