ClickTech DNA FISH Kit 555 - 1 Kit

Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique that enables the detection and localization of specific DNA or RNA sequences within cells/tissues. DNA FISH is a very important tool not only for basic research, but also for clinical applications such as cytogenetic screening for diagnosis and prognosis of cancer (Oliveira and French 2005) and genetic syndromes (Volpi and Bridger 2008a), including prenatal screening. The principle of DNA FISH is to hybridize small single stranded DNA molecules (probes) to complementary sequences on chromosome spreads or in nuclei of whole cells (target), which are immobilized on glass slides. The probes are labeled directly or indirectly using fluorescent or radioactive nucleotides or through fluorescent antibodies (Volpi and Bridger 2008b). After labeling, FISH probes and targets are thermally denatured and hybridized. The standard FISH technique, however, often suffers from limitations, namely poor signal to background n
