Innovation: Photoactivatable fluorescent proteins.Nat Rev Mol Cell Biol. 2005 Nov; 6(11):885-91.NR
The fluorescence characteristics of photoactivatable proteins can be controlled by irradiating them with light of a specific wavelength, intensity and duration. This provides unique possibilities for the optical labelling and tracking of living cells, organelles and intracellular molecules in a spatio-temporal manner. Here, we discuss the properties of the available photoactivatable fluorescent proteins and their potential applications.
