Today researchers are eager to know which proteins are the brightest and what the best excitation wavelengths are. Here we review the two-photon absorption properties of a wide variety of fluorescent proteins, including new far-red variants, to produce a comprehensive guide to choosing the right fluorescent protein and excitation wavelength for two-photon applications.
