Study of the on-off photoswitching of mEmerald at cryogenic temperature

mEmerald is a GFP-derived fluorescent protein that showed a tendency to reversibly photoswitch between an "on" fluorescent state and an "off" non-fluorescent state under...mEmerald是一种源自绿色荧光蛋白（Green Fluorescent Protein，GFP）的荧光蛋白，其呈现出在"开启"荧光状态与"关闭"非荧光状态之间发生可逆光开关的倾向，在……
