Fluorescence In Situ Hybridization (FISH)

Fluorescence In Situ Hybridization (FISH) is a laboratory technique used to detect and localize specific DNA or RNA sequences within cells. It involves using fluorescently labeled probes that bind to targeted genetic materials. When viewed under a fluorescence microscope, these probes light up, allowing researchers to see the presence and location of the genes of interest. FISH is commonly used in genetics, cancer research, and prenatal testing to identify chromosomal abnormalities and gene expressions, enhancing our understanding of various diseases and conditions.
