GF 109203X (GF-109) was used to clarify an impact of PKC on average open time of GABA-A receptor channel. Experiment on outside-out membrane patches (OOP) and nucleated patches (NP) excised from hippocampal granule cells displayed a significant effect of GF-109 in NPs only. This confirms modulation of GABA-A receptor opening by PKA and ensures absence of GF-109 side effects on GABA-A receptors (since no effect was observed in OOPs).
