    Novel caged-glutamate compound, uncaged by visible light
  • Biological description
    Novel caged-glutamate compound based on ruthenium photochemistry. Excited with visible wavelengths and releases glutamate after one- or two-photon excitation. It has high quantum efficiency and can be used at low concentrations. Enables the photoactivation of neuronal dendrites and circuits with visible or two-photon light sources, achieving single cell, or even single spine, precision.

    Also available in simple stock solutions (ab146718) - add 1 ml of water to get an exact, ready-to-use concentration.
  • General notes

    RuBi-Glutamate is light sensitive and it is recommended that the compound is protected from light.
