Excerpts

Together, eqFP578 and eqFP611 represent a separate group of red fluorescent proteins, which are characterized by high fluorescence brightness, complete chromophore maturation and, notably, a reduced tendency to oligomerize. These features make E. quadricolor fluorescent proteins an attractive starting point for the generation of bright monomeric red fluorescent proteins.
