Compared to other tests, southern blot is a complex technique that has multiple steps and these steps require equipment and reagents that are expensive. [10] High quality and large amounts of DNA are needed. [10] Southern blotting is a time consuming method and can only estimate the size of the DNA since it is a semi-quantitative method. [10]
Sir Edwin Mellor Southern FRS FRSE (born 7 June 1938) [4] is an English Lasker Award-winning molecular biologist, Emeritus Professor of Biochemistry at the University of Oxford and a fellow of Trinity College, Oxford. He is most widely known for the invention of the Southern blot, published in 1975 [5] and now a common laboratory procedure. [6 ...
A Southern blot is a method routinely used in molecular biology for detection of a specific DNA sequence in DNA samples. Southern blotting combines transfer of electrophoresis-separated DNA fragments to a filter membrane and subsequent fragment detection by probe hybridization. [1]
It acts as a probe for the presence of the target in a Southern blot assay or, more commonly, in the simpler dot blot assay. It is a common tool used in genetic testing, forensics, and molecular biology research. An ASO is typically an oligonucleotide of 15–21 nucleotide bases in length.
The DNA fragments produced by the digest are then separated by length through a process known as agarose gel electrophoresis and transferred to a membrane via the Southern blot procedure. Hybridization of the membrane to a labeled DNA probe then determines the length of the fragments which are complementary to the probe. A restriction fragment ...

Named after its inventor, biologist Edwin Southern, the Southern blot is a method for probing for the presence of a specific DNA sequence within a DNA sample. DNA samples before or after restriction enzyme (restriction endonuclease) digestion are separated by gel electrophoresis and then transferred to a membrane by blotting via capillary action.
