Fluorescence In Situ Hybridization

Fluorescence In Situ Hybridization (FISH) is a laboratory technique used to detect specific DNA sequences within cells. Scientists use tiny, fluorescently labeled DNA probes that bind to matching genetic regions on chromosomes. Under a special microscope, these fluorescent probes glow, allowing researchers to see the exact location of specific genes or genetic changes. FISH is commonly used for diagnosing genetic disorders, detecting cancer-related genetic mutations, or studying chromosome structure, providing precise and visual information about genetic material within cells.
