As expected, a solid fluorescence indication was observed over 1.5mins after stopping the stream of labelled wt7D12, in keeping with receptormediated localisation of wt7D12 (Amount4E). the mutants. Finally, we demonstrate the use of photoactive antibodies in providing fluorophores to EGFRpositive live cancers cells within a lightdependent way.
