• GABAA a1b2g2

    Concentration dependent activation and desensitization of GABAA (α1β2γ2) receptors by application of 1, 3 and 10 μM GABA as measured on the Port-a-Patch)

GABAA Receptor - Stacked Application Technology

p36 3 timedIntervicon pl   Patchliner data and applications:

Ligand gated ion channels often display receptor desensitization. A method was developed to minimize ligand exposure times and intervals between ligand exposures. The pipette first aspirates buffer, then compound. When expelling this stack, the cell is first exposed to ligand and then buffer. Exposure times as low as 400 ms are possible with this method. A GABA dose response curve, aquired in this manner, is shown on the left.
