Fluorescence in situ hybridization (FISH) is a technique pathologists use in genetic testing to help diagnose diseases caused by chromosomal differences. Healthcare providers can also use FISH to detect gene changes that they can target to treat cancer.
How exactly does FISH work? Aa Aa Aa. Cytogenetics entered the molecular era with the introduction of in situ hybridization, a procedure that allows researchers to locate the positions of...
How does FISH work? FISH is useful, for example, to help a researcher or clinician identify where a particular gene falls within an individual's chromosomes. The first step is to prepare short sequences of single-stranded DNA that match a portion of the gene the researcher is looking for.
Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique that allows the localization of a specific DNA sequence or an entire chromosome in a cell.
Fluorescence in situ hybridization (FISH) is a laboratory-based test that can reveal the genetic makeup of a cancer. Sanam Loghavi, M.D., explains how the results help with diagnosis, developing a treatment plan and even post-treatment surveillance.
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.
Fluorescence in situ hybridization (FISH) testing is a molecular pathology test that helps identify specific genes in a person’s cells. It can show how genes have changed and whether there...
