Western blotting is a technique used to identify a specific protein in a mixture of different proteins. This technique involves separating the proteins by size using gel electrophoresis, transferring the separated proteins onto a membrane, and then probing the membrane with a specific antibody that recognizes the protein of interest. The antibody binds to the protein, allowing it to be detected using various methods (e.g. chemiluminescence). Northern blotting is used for RNA detection, Southern blotting is used for DNA detection, and Eastern blotting is not a commonly used or recognized technique.
