Electropherograms for a competitive binding immunoassay performed by CE in which clenbuterol tagged with FITC was used as the labeled analog. In (A) only labeled clenbuterol was injected onto the CE system, as represented by peak 1. In (B) a mixture of labeled clenbuterol, anti-clenbuterol antibodies, and a sample containing clenbuterol was injected, where the immune complex between the labeled clenbuteron and the antibodies is represented by peak 2.
