Southern blotting, developed by Sir Edward M. Southern in 1975, is a molecular technique used to detect specific DNA sequences. It involves transferring DNA from a gel to a nitrocellulose membrane, followed by hybridization with radiolabeled probes. This method is pivotal in DNA analysis, forensic science, and paternity testing.

Blotting Technique: Understanding and Applying Blotting Techniques for Molecular Analysis
Blotting is used in molecular biology to transfer nucleic acids and proteins from gel to a membrane for identification and analysis. Developed in the 1970s, it combines electrophoresis and immunological methods. There are three main types: Southern (DNA), Northern (RNA), and Western (proteins), each allowing detection and measurement of specific molecules.
