A method developed by EM Southern for detecting and manipulating specific DNA sequences previously separated by gel electrophoresis using a radioactively- or chemically-labeled DNA probe with sequence similarity

Southern blot

a technique for detecting specific DNA sequences following agar gel electrophoresis of a set of DNA restriction enzyme digestion fragments. The fragments after electrophoresis are transferred to a nitrocellulose or nylon membrane by applying the membrane to the gel; the membrane is probed with a radioprobe that hybridizes to one or more of the separated fragments and used to produce an autoradiogram. Named for Edward Southern.
