WebAs shown in Fig. 1, introducing a time delay of approximately 50 to 150 µ seconds between the system excitation and fluorescence measurement allows the signal to be cleared of all non-specific short-lived emissions. In contrast, HTRF acceptors emit long-lived fluorescence when engaged in a FRET process.
