Excerpts

A drawback of mPapaya0.6 that soon became apparent was relatively poor photostability under typical live cell imaging conditions. Similar to mTFP0.7, photobleached mPapaya0.6 displayed a 410 nm absorbance peak attributable to the protonated state of the chromophore and was observed to recover fluorescence when stored in the dark
