FISH analysis

FISH analysis, or Fluorescence In Situ Hybridization, is a laboratory technique used to detect and visualize specific DNA sequences in chromosomes. This method involves attaching fluorescent dyes to DNA probes that bind to targeted areas of chromosomes within cells. When illuminated under a special microscope, these dyes glow, revealing the presence, number, or arrangement of specific genes. FISH is commonly used in genetics and medical research to identify genetic abnormalities, such as those involved in cancer or inherited diseases, helping researchers and clinicians better understand genetic conditions and guide treatment decisions.
