Nitrobenzyl-caged ABT 594 (Cat. No. 6576), a selective α4β2 nAChR agonist. Suitable for one- or two-photon photolysis. Evokes large inward currents and Ca2+ transients on cell bodies and dendrites of medial habenular neurons in mouse brain slices, following exposure to 410 nm light. Two-photon uncaging at 720 nm induces fast nAChR-mediated currents. Photolyzed with high quantum yield of 0.20. Purity 98%. MW (observed): 672.16
