There was a report a couple years ago in Nature
Adams, S. R., A. T. Harootunian, Y. J. Buechler, S. S. Taylor, and
R. Y. Tsien. 1991. Fluorescence ratio imaging of cyclic AMP in
single cells. Nature 349:694-697.
They labelled the R and C subunits of A kinase with different dyes
then measured the decrease in energy transfer as the subunits dissociated
on binding cAMP. This resulted in a dequenching and an increase
I recently saw an ad from some company that appeared to be using
this method. Unfortunately I don't recall the details (i.e. which
company). You might contact Roger Tsien or Susan Taylor to find
out who they sold the license to (as I suspect that is the
