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]
The second diagram shows how this fragment size variation would look on a Southern blot, and how each allele (two per individual) might be inherited in members of a family. In the third schematic, the probe and restriction enzyme are chosen to detect a region of the genome that includes a variable number tandem repeat (VNTR) segment (boxes in ...

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]
This process is termed Southern blotting. For fluorescent dyes, after electrophoresis the gel is illuminated with an ultraviolet lamp (usually by placing it on a light box, while using protective gear to limit exposure to ultraviolet radiation). The illuminator apparatus mostly also contains imaging apparatus that takes an image of the gel ...
Bulked DNA samples can be analysed using Southern blotting.Use of restriction enzymes or PCR amplification on the DNA is required for RFLP or RAPD analysis respectively. In these techniques, the loci that are analysed are the restriction digest sites and the sequences on which PCR primers attach to.
Restriction digest is most commonly used as part of the process of the molecular cloning of DNA fragment into a vector (such as a cloning vector or an expression vector).The vector typically contains a multiple cloning site where many restriction site may be found, and a foreign piece of DNA may be inserted into the vector by first cutting the restriction sites in the vector as well the DNA ...
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.
