Abstract
Photochromic fluorescent protein moiety having two or more stable states having excitation or emission spectra that are shifted from one wavelength region to another wavelength region in the two states are described. The photochromic material switches between states by irradiation with light of appropriate wavelengths. The two states are preferably stable at room temperature and in the dark. The switching between states can be reversible.
