NMDA (Cat.No. 0114) caged with the photosensitive 4-methoxy-7-nitroindolinyl group. Stoichiometrically releases chirally pure NMDA. Suitable for uncaging with 300-380 nm excitation. Improved localization can be achieved by uncaging at 405 nm (with mM concentration of caged compound in the bath solution). Exhibits rapid uncaging rate relative to ionotropic glutamate receptor activation. Purity 99%. MW (observed): 323.3
