    • The DBO chromophore has the additional advantage, owing to its exceedingly long fluorescence lifetime, of being amenable to detection by nanosecond time-resolved fluorescence (Nano-TRF), which can lead to an improved background suppression and increased robustness of enzyme assays; cf. Hennig, A.; Roth, D.; Enderle, T.; Nau, W. M. ChemBioChem 2006, 7, 733-737.

    • To further identify false negatives, a secondary screening is routinely performed in high-throughput applications. In the case of supramolecular tandem assays, this could be done in the simplest case by adding the reporter pair after incubation with the enzyme. Such an additional single-point determination would conveniently eliminate the influence of the inhibitor-macrocycle binding on the enzyme kinetics. Alternatively, a secondary screen with a different reporter pair could be performed.
