Far-western Blotting

Far-western blotting is a molecular biological method which is based on the technique of western blotting to detect protein-protein interaction in vitro. While usual western blotting uses an antibody to detect a protein of interest, far-western blotting uses a non-antibody protein, which can bind the protein of interest. Thus, whereas western blotting is used for the detection of certain proteins, far-western blotting is rather employed to detect protein:protein interactions.
