Epitope tags provide a method to localize gene products in a variety of cell types, study the topology of proteins and protein complexes, identify associated proteins, and characterize newly identified, low abundance or poorly immunogenic proteins when protein specific antibodies are not available. Epitope tag detection with an unconjugated antibody requires the use of a secondary antibody that carries a reporter for detection. Unconjugated antibodies let you choose the detection method which best suits your needs. They are also useful for the detection of weak signals, since a secondary antibody can amplify the signal.
