Applications

  • Application notes

    The AMPAR positive allosteric modulator Cyclothiazide increases the open time of the AMPAR by inhibiting AMPAR desensitization. It is often used at a concentration of 100 μM. Cyclothiazide from Hello Bio potentiates AMPAR mediated evoked EPSCs in cortical neurons at 50 μM and above (see Fig 1 above)

     

    #Protocol 1: Evoked and spontaneous evoked 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 mV (the reversal potential of GABA currents).
    • EPSCs were then continuously stimulated and recorded in response to 5 min applications of 50 μM and then 100 μM Cyclothiazide.
