Brief Introduction: Blotting Techniques. Southern, Northern, and Western are three blotting techniques used to detect a specific DNA, RNA or protein molecule in a sample. The main difference between Southern Northern and Western blotting is that the Southern blotting involves the identification of DNA, and the Northern blotting involves the identification of RNA, whereas the Western blotting involves the identification of proteins. Different blotting techniques are used to identify unique proteins and nucleic acid sequences.
