MNI-caged glutamate that rapidly and efficiently releases glutamate (Cat.No. 0218) when photolysed (300 - 380 nm excitation). Water-soluble, highly resistant to hydrolysis, stable at neutral pH, and pharmacologically inactive at neuronal glutamate receptors (up to mM concentrations). 2.5-fold more efficient at releasing L-glutamate than NI-caged L-glutamate.
