NBQX disodium salt produced by Hello Bio produced a very potent and "clean" block of synaptic AMPA currents, with no effect on other GABAA or NMDA receptors.Verified customer, The University of Edinburgh
The AMPA receptor antagonist NBQX disodium salt inhibits the actions of glutamate by acting at AMPARs and is commonly used at 10 μM. NBQX disodium salt from Hello Bio inhibits spontaneous and evoked excitatory post synaptic currents (EPSCs) (see Fig 1 above). Complete AMPA receptor blockade was achieved at 10 μM and NBQX disodium salt was also effective at reducing these currents at 1 μM.
#Protocol 1: Evoked and spontaneous excitatory post synaptic currents (EPSCs)
Whole cell voltage clamp recordings were obtained from layer V neurons of the mouse prelimbic cortex brain slice.
EPSCs were evoked via a stimulating electrode placed in layers II/III delivering a single square (150 μs) pulse every 10 sec at an intensity that gave a reliable EPSC.
Neurons were held at -70 to -60 mV (the reversal potential of GABA currents). EPSCs were continuously stimulated and recorded in response to 5 min applications of varying concentrations of NBQX disodium salt until complete receptor inhibition.
Spontaneous EPSCs were recorded before and after addition of NBQX disodium salt by holding the neuron at -70 mV and recording for 10 sec.
Recordings for EPSCs were made in the absence of GABAA-R antagonists.
