Fluorescence In Situ Hybridization (FISH) is a powerful molecular/cytogenetic technique that utilizes a fluorescent-labeled DNA probe to ascertain the presence or absence of a particular segment of DNA. ... The Genetics Center FISH laboratory is also equipped to test for many types of leukemia.

What is the purpose of cytogenetics?

The purpose of cytogenetics is to study the structure and normal and pathological functioning of chromosomes (condensation, recombination, repair, segregation, transmission) and chromatin (organization and role in the regulation of gene expression).

What is FISH used for genetics?

Fluorescence in situ hybridization (FISH) provides researchers with a way to visualize and map the genetic material in an individual's cells, including specific genes or portions of genes. This may be used for understanding a variety of chromosomal abnormalities and other genetic mutations.
