Figure 1. (+)-MK 801 inhibition of evoked NMDAR mediated EPSCs in mouse cortical neuron
The NMDA receptor antagonist (+)-MK 801 is use-dependent and blocks NMDARs in their open conformation. (+)-MK 801 from Hello Bio fully abolishes evoked NMDAR currents at 10 µM rapidly upon repeated stimulations. At concentrations of 50 µM a more rapid receptor blockade was observed. For assay protocol, see #Protocol 1 in Application Notes below

Biological Data
Biological description
Potent, selective and non-competitive NMDA receptor antagonist (Kd = 37.2 nM). Approx 10-fold more potent than (-)-MK 801 maleate. Prevents calcium ion influx and long term potentiation induction. Shows anticonvulsant and neuroprotective properties.
Application notes
The NMDA receptor antagonist (+)-MK 801 is use-dependent and blocks NMDARs in their open conformation.
(+)-MK 801 from Hello Bio fully abolishes evoked NMDAR currents at 10 μM rapidly upon repeated stimulations (see Fig 1 above). At concentrations of 50 μM a more rapid receptor blockade was observed.
#Protocol 1: Evoked NMDA receptor currents
Whole cell voltage clamp recordings were obtained from layer V neurons of the mouse prelimbic cortex brain slice.
NMDA currents were evoked via a stimulating electrode placed in layers II/III and evoked by a single square (150 μs) pulse every 10 sec at a stimulus intensity that gave a reliable NMDA current.
Neurons were held at +40 mV to relieve NMDA currents from their voltage-dependent Mg2+ block.
NMDA currents were continually stimulated and recorded in response to continual bath applications of (+)-MK 801 until NMDA currents were completely abolished.
All NMDAR recordings were made in the presence of GABAA-R and AMPAR antagonists.
