FISH (Fluorescence In Situ Hybridization)

Fluorescence In Situ Hybridization (FISH) is a laboratory technique used to detect and visualize the presence and location of specific DNA or RNA sequences in cells or tissue samples. By using fluorescent probes that bind to these genetic sequences, scientists can observe them under a special microscope. This method is valuable in genetics and medical research for diagnosing diseases, identifying genetic abnormalities, and studying the structure and function of chromosomes. FISH helps provide insights into cellular processes and can aid in understanding conditions like cancer and genetic disorders.
