Partial block of AMPARs.
By Sergiy Sylantyev on 12/15/2020
Assay Type: In Vitro
Species: Rat
Cell Line/Tissue: Cerebellar granule cell

NBQX was used to block evoked AMPA-receptor response in outside-out membrane patches excised from hippocampal granule cells. 0.1 µM concentration caused an immediate partial block (see illustration). Highly specific and potent ligand, but requires long sonication to prepare 10 mM DMSO stock.Illustration: I - control AMPAR response at -60 mV cell membrane potential; II - control AMPAR response at +40 mV cell membrane potential; III - NBQX at -60 mV cell membrane potential; IV - NBQX at +40 mV cell membrane potential.
