Hello
If you look at the literature, majority of the time Cerulean and Venus is used as a FRET pair. The CFP is not a good donor for lifetime since it provides double exponential decays.
Cerulean3 and mTFP also used as a donor and Venus as an acceptor. Venus and tdTomato is another good FRET pair too. Please see some of our publications for various FRET pairs

Dear all,

This question has been asked in the past already. But the color palette of XFPs has increased substantially in the meantime.
Which combination of FPs is considered the best FRET pair right now?
Maybe one should also seperate between acceptor bleaching, sensitized emission (ie filter fret) and FLIM, since the demands are quite different for the three methods.
Any input is very welcome!
