FIGURE 2.
GABA concentration dependence of non-concatenated receptors expressed in Xenopus oocytes. Averaged GABA concentration-response curves of α1/β3, α1/β3/δ, α6/β3, and α6/β3/δ receptors are shown. Individual curves were first normalized to the observed maximal current amplitude and subsequently averaged. Mean ± S.D. of experiments carried out with 3–4 oocytes from two batches for each subunit combination is shown.
