||"...[investigators] combined the monomeric red fluorescent protein mCherry, which matures with a half-time of ~40 min [primary source], with a monomeric variant of the superfolder green fluorescent protein sfGFP, which becomes fluorescent within minutes of synthesis [ref 18]. A pool of mCherry-sfGFP molecules should be mostly green-fluorescent shortly after synthesis and gradually acquire red fluorescence over time, such that the ratio of red to green fluorescence is a function of the age of the protein pool (Fig. 1b)."
