Epitope mapping by surface plasmon resonance.
Biacore systems (Biacore AB) enable label-free detection of molecular interactions in real time using surface plasmon resonance detection. Epitope mapping of antibodies is usually performed in a pairwise fashion where one antibody is used to capture the antigen from solution and the binding of a secondary antibody is monitored. In contrast to alternative approaches, the method allows for mapping of large matrices of antibody pairs without the need for cumbersome labeling steps, and the real-time analysis enables a better ranking of complex stability when compared with end-point assays.
