A procedure for identifying specific sequences of DNA, in which fragments separated on a gel are transferred directly to a second medium on which assay by hybridization may be carried out.
- ‘Standard techniques were used for DNA cloning, restriction enzyme digestion, Southern blot analysis, and DNA sequencing.’
- ‘The assay is similar to the Southern blot except that restriction enzyme digestion and denaturation of the mRNA are not needed.’
- ‘Columns of horizontal ovals and rectangles indicate lack of hybridization on the Southern blots.’
- ‘Standard molecular biological procedures, such as Southern blots, were performed as described.’
- ‘In Southern blots, DNA is cut with restriction enzymes then separated.’
Late 20th century: named after Edwin M. Southern (born 1938), British biochemist.
