Fluorescent proteins have been used extensively in many areas of life sciences. Many of their applications rely on their various biophysical properties, such as excitation and emission wavelengths, excited state lifetimes, or sensitivity to the molecular environment. One aspect of fluorescent proteins that has remained largely neglected is the directionality of their optical properties. In the present work, we describe our experimental determination of the directionality of light absorption and emission in several commonly used fluorescent proteins. Our findings improve our understanding of fundamental properties of fluorescent proteins, and expand the possibilities of development and applications of genetically encoded fluorescent probes.
