Southern Blotting
Electrophoresis separates DNA by size but does not provide any information about the nucleotide sequence in the DNA.

Southern hybridization (Southern blotting).

Southern blotting
Transfer by absorption of DNA fragments separated in electrophoretic gels to membrane filters for detection of specific base sequences by radio-labeled complementary probes.

[edit] Southern blotting
Main article: Southern blot
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.

Southern blotting is a laboratory technique used to detect a specific DNA sequence in a blood or tissue sample. A restriction enzyme is used to cut a sample of DNA into fragments that are separated using gel electrophoresis.

Southern blotting - technique in which DNA fragments, separated by electrophoresis, are immobilized on a paper sheet; specific molecules are then detected with a labeled nucleic acid probe ...

Southern blotting
Scientists often use southern blots to evaluate DNA extracts from tissue samples (Fig. 7). Southern blotting a type of nucleic acid hybridization test, in which single-stranded DNA from two sources interact.

Heat DNA on the gel to unwind and make single stranded DNA
A nylon membrane placed over the gel is covered with absorbent paper / single stranded fragments are transferred to membrane by capillary action ...

The maps are composed largely of named genes identified by recombinant DNA probes in Southern blotting assays. Hundreds of genes are being placed each year.

Autoradiography
A technique that uses X-ray film to visualize radioactively labeled molecules or fragments of molecules; used in analyzing length and number of DNA fragments after they are separated by gel electrophoresis. See Southern blotting.

endonucleases, which only cut where there are specific DNA sequences recognized by the enzymes. The restriction fragments are then separated according to length by agarose gel electrophoresis. The resulting gel may be enhanced by Southern blotting.

of a radiol abeled (or chemiluminescent) dexoynucleotide (dNTP) will yield probes representing the sequences found in the template DNA. The labeled probes can then be used to identify other sequences homologous to this DNA (e.g. by Southern blotting).

Normally detected by Southern blotting and probing. Used in detection of genetic disease alleles etc.
RT-PCRPCR amplification from an RNA template.

Southern blotting -- a technique for transferring electrophoretically resolved DNA segments from an agarose gel to a nitrocellulose filter paper sheet via capillary action; the DNA segment of interest is probed with a radioactive, ...
