Southern blot - Wikipedia, the free encyclopedia
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 fragment...

Southern blotting was named after Edward M. Southern who developed this procedure at Edinburgh University in the 1970s. To oversimplify, DNA molecules are transferred from an agarose gel onto a membrane. Southern blotting is designed to locate a particular sequence of DNA within a complex mixture.

The Southern blot is used to detect the presence of a particular bit of DNA in a sample. The DNA detected can be a single gene, or it can be part of a larger piece of DNA such as a viral genome.

2) The DNA is transfered to a membrane which is a sheet of special blotting paper. The DNA fragementsw retain the same pattern of separation they had on the gel. ... This is a brief overview of how a Southern blot (more formally called an DNA blot) is performed and what type of data you can obtain form one.
