Abstract

We found that photoconversion is fairly common among orange and red fluorescent proteins, as in a screen of 12 proteins, 8 exhibited photoconversion. Specifically, three red fluorescent proteins could be switched to a green state, and two orange variants could be photoconverted to a far-red state. The orange proteins are ideal for dual-probe highlighter applications, and they exhibited the most red-shifted excitation of all fluorescent proteins described to date.
