Detection of Specific DNA Sequences — The Southern Blot

Southern Blotting Principle: Southern blotting is an example of RFLP (restriction fragment length polymorphism). It was developed by Edward M. Southern (1975) Southern blot — A test commonly used in molecular biology and genetics, the purpose of the test being to check for a match between DNA molecules. In the Southern blot technique, DNA fragments are separated by a method called agarose gel electrophoresis, Medical dictionar A Southern blot is a way to analyze DNA molecules. The protocol was developed by Edward Southern. And if you were going to perform a Southern blot, you would first want to separate DNA based upon size in a gel along an electric field... And so your larger fragments, again, at the top; your smaller fragments are going to be at the bottom. When you're done running your gel, you then transfer.

Biochem. 210(2), 235-244 Analys of Genomic DNA by Southern Hybridization (Southern Blot) Outline: Localization of particular sequences within genomic DNA is usually accomplished by the transfer techniques described by Southern (1975). Genomic DNA is digested with one or more restriction enzymes, and the resulting fragments are separated according to size by electrophoresis through an agarose gel. The DNA is then denatured in situ and transferred from the gel to a solid support (usually nitrocellulose filter or nylon.

The DIG-System can detect 0.03 pg (chemiluminescent detection) or 0.1 pg (colorimetric detection) homologous DNA in a Southern blot format on a nylon membrane. This corres-ponds to the detection of a single-copy gene in <1 µg of human genomic DNA. The proced-ures described here, are used routinely in our labs and have been found to give optimal results in Southern blotting, particularly in genomic Southern blotting Die im Rahmen dieser Arbeit durchgeführten Southern Blot Analysen sollten die PCR-Daten bestätigen und zur weiteren Charakterisierung der Bruchpunktregion führen.

It was first described by E. M. Southern in 1975 At a meeting recently, I asked two PhD molecular biologists about the last time they used a Southern blot. After nearly a minute of unrestrained laughter, they asked Who on earth still does that? Maybe for a very, very specific use, conjectured one of the scientists. When I asked the scientist who taught me the technique a very long time ago, she was a little more thoughtful: I.

We have adopted the Southern blot method for the measurement racy, specificity, limit of detection, linearity and dynamic range. Accuracy in measuring the absolute length of telomeres is especially important for facilitating comparisons of findings across studies in diverse populations and in setting thresholds for telomere size that might eventually impact clinical decisions (if and when. Detection methods differ based on the probe label; radiolabeled probes are visualized with X-ray film or phosphorimaging, and enzymatically labeled probes are visualized with chemiluminescent substrate. Southern blot protocol. DNA isolation; Restriction digestion: digest the DNA with a restriction enzyme, and if necessary, concentrate digested DNA. Gel electrophoresis: prepare an agarose gel. Southern blot remains the gold standard technique for cccDNA detection, as it can separate the cccDNA from protein-free (aka deproteinized) relaxed circular DNA (rcDNA) through electrophoresis. This protocol was originally published in Methods in Molecular Biology: Antiviral Methods and protocols ( 4 ) 1 The technique has come to be known as the Southern transfer or Southern blot, and has had an enormous impact on molecular biology and genetics. The purpose of this technique is the detection and characterization of specific DNA sequences. The primary purpose of southern blot is to detect a sequence of DNA in a given DNA sample.

Tiling approach to Southern blot probe design. Many potential probes are generated and tested in the user-specified genomic window, starting from the maximum allowable probe length (default 1300), tiling the window by moving by a small percentage of the probe length each time (default 5%). Once this is completed the probe length is reduced by 50 bases (configurable) and the window re-tiled. The Southern blot is used to detect a specific DNA sequence in DNA samples.
