AX0010033 by Applied Biological Materials is a 1.0 µg P2A expression plasmid co-expressing YFP (excitation ~514 nm, emission ~527 nm), LOCa3 (light-operated calcium actuator), and mKate2 (far-red expression marker; excitation ~588 nm, emission ~633 nm) as separate proteins. For optogenetic calcium actuation with multi-spectral expression tracking. mKate2 far-red marker is spectrally orthogonal to GFP/GCaMP indicators for multi-color experimental design.
