Features：The response speed is fast and it can activate neurons at high frequency, the activation intensity (inward current) is also larger than that of the commonly used ChrimsonR. ChroME2f is an opsin mutant ChroME S273A. It can support large-scale, temporally precise multiphoton excitation in the intact brains of awake animals. 

Gene/Insert name：ChroME2
Tag/Fusion protein：mRuby3
Titer：>1x10^13 VG/mL，>2x10^12 VG/mL
Volume：100μL
