Rapidly and efficiently releases glutamate when photolysed (350 - 365 nm excitation). Water soluble and stable at neutral pH, and pharmacologically inactive at neuronal glutamate receptors (up to 200 μM). 5.5 times more photosensitive than MNI-caged L-glutamate . Laser activation of MDNI-glu evokes a rapid increase in intracellular Ca2+ concentration in astrocytes.
