详情描述
CNQX (FG9065) is a potent and competitive AMPA/kainate receptor antagonist with IC50s of 0.3 μM and 1.5 μM, respectively. CNQX is a competitive non-NMDA receptor antagonist. CNQX blocks the expression of fear-potentiated startle in rats.

How to use
In Vitro:
CNQX (FG9065; 2-5 μM) reversibly blocks the Schaffer collateral and mossy fibre excitatory postsynaptic potential (EPSP), while sparing the fast and slow GABA-mediated inhibition in superfusion of hippocampal slices. CNQX (1-5 μM) produces a selective and dose-dependent reduction in the amplitude of the monosynaptic component of the DR-VRR recorded from lumbar spinal segments.
