What is fluorescence in situ hybridization?

Fluorescence in situ hybridization (FISH) is a method for displaying the presence and content of DNA in the nucleus or on a chromosome by using a nucleic acid probe hybridization principle using a non-radioactive fluorescent substance. The technology is fast, safe, sensitive and long-term storage of probes. It has been widely used in cytogenetics, tumor biology, gene mapping, gene mapping, prenatal diagnosis and mammalian chromosome evolution research.
