Biological Activity for RuBi-Glutamate

RuBi-Glutamate is a ruthenium-bipyridine-trimethylphosphine caged glutamate that can be excited by visible wavelengths and releases glutamate after one- or two-photon excitation. Has high quantum efficiency and can be used at low concentrations, partly avoiding blockade of GABAergic transmission seen with other caged glutamate compounds. Displays high spatial resolution and generates excitatory responses in individual dendritic spines with physiological kinetics.

MNI-caged-L-glutamate (Cat. No. 1490) also available.
