    CNQX disodium purchased from MedChemExpress. Usage Cited in: Nat Commun. 2024 May 15;15(1):4122.  [Abstract]

    Light-evoked EPSCs in vCE L5a PCs were abolished after bath application of tetrodotoxin (TTX) but were then reintroduced following application of 4-Aminopyridine, indicating the monosynaptic nature of connections from V2 to vCE L5a. These restored responses were blocked by AMPA receptor antagonist CNQX.

    The light-evoked EPSCs were abolished by TTX and rescued by 4-AP, but severely attenuated by CNQX.

    製品説明

    CNQX disodium (FG9065 disodium) is a potent and competitive AMPA/kainate receptor antagonist with IC50s of 0.3 μM and 1.5 μM, respectively. CNQX disodium is a competitive non-NMDA receptor antagonist[1]. CNQX disodium blocks the expression of fear-potentiated startle in rats[5].

    体外実験

    CNQX disodium (FG9065 disodium; 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[2].
    CNQX disodium (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[3].

    体内実験

    CNQX disodium (FG9065 disodium; 0.75-3 mg/kg; IP; 20 min before testing) decreased the number of cocaine responses in a dose-dependent manner during the first 15-min cocaine-free interval[4].
    The bilateral infusion of CNQX disodium (0.5 or 1.25 μg) into the amygdala or dorsal hippocampus 10 min prior to a retention test partially blocks the expression of stepdown inhibitory avoidance in rats 24 h after training. CNQX disodium causes a complete blockade at a dose of 0.5 μg[5].

    Animal Model: Male Wistar rats weighing 180-200 g[4]
    Dosage: 0.75, 1.5, and 3 mg/kg
    Administration: IP; 20 min before testing
    Result: Decreased the number of cocaine (IV; 0.25 mg/infusion) responses in a dose-dependent manner during the first 15-min cocaine-free interval.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
