WebFeb 9, 2024 · An advantage of FISH is that it doesn't have to be performed on cells that are actively dividing. Cytogenetic testing usually takes about three weeks, because the cancer cells must grow in lab dishes for about 2 weeks before they can be tested. In contrast, FISH results are usually available from the lab within a few days. 7 7 Sources WebSummary: The FISH (Fluorescence in situ hybridization) or Cytogenetics Technologist handles performing all aspects of testing and analysis in the FISH laboratory; wet lab …

Necessary are always a target-DNA (metaphases or interphases, or for molecular combing (see below) DNA-fibers) and a probe-DNA.
Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique that uses fluorescent probes that bind to only particular parts of a nucleic acid sequence with a high degree of sequence complementarity. It was developed by biomedical researchers in the early 1980s to detect and localize the presence or absence of specific DNA sequences on chromosomes.
