There will be a spectral shift depending on the distance of the
fluorophores. E.g. FITC-Emission generated by an PLA1
alloantibody will be absorbed by an anti-GpIIb/IIIa monoclonal
depending on distance of the epitopes. The method can
be used for the characterization of human anti-platelet
antibodies. We published the method in
J. Immunol. Methods 187: 53-67, 1995.
