Figure 1From: Biochemical characterization and cellular imaging of a novel, membrane permeable fluorescent cAMP analogFluorescence absorption and emission spectra of the Pharos dye. The absorption maxima of the Pharos dye dissolved in buffer with the indicated pH values is at 575 nm, whereas the emission maxima are at 617 nm. All spectra exhibit a large Stokes shift of 42 nm.Back to article page
