Fluorescent proteins with excitation and emission maxima in the near-infrared would be especially useful because of the low light absorbance of mammalian tissues in this optical window. Verkhusha and colleagues present a bright, photostable fluorescent protein with optimized near-infrared spectra that does not require the addition of exogenous co-factors.
