Technique that uses antibodies (or other specific ligands in related techniques) to identify target proteins among a number of unrelated protein species.
Note: The techniques allow the detection of proteins from complex mixtures separated by gel chromatography and then transferred to a membrane. After incubation of the attached product from membrane with labelled antibody, the target proteins become visible.
