Southern blotting is a technique used to identify a specific DNA sequence from a sample. The process involves digesting the DNA with restriction enzymes, separating it using gel electrophoresis, and then transferring the DNA from the gel to a membrane. The membrane is then hybridized with a labeled probe that specifically binds to the DNA sequence of interest, allowing for its identification. Western blotting is used to detect specific proteins, not DNA sequences. Northern blotting is used to detect specific RNA sequences. Eastern blotting is not a commonly used technique in molecular biology.
