Frontispiece: Primed Conversion: The New Kid on the Block for Photoconversion

Primed conversion is a novel way to photoconvert fluorescent proteins from green to red. For this process to happen the chromophore (buried inside the β‐barrel of the fluorescent protein) needs to sequentially absorb two photons of different color. It is only when blue and far‐red light intercept that conversion from green to red fluorescence can take place. In their Minireview on page 8268 ff., M. A. Mohr and P. Pantazis discuss what is known about this process to date, why and when it is useful, and include its advantages and disadvantages.
