Abstract: | The binding of n concentrations of 3HGABA and 3Hmuscimol to synaptosomal membrane preparations from different areas of rat brain were studied by a radioreceptor assay. The characteristics of binding, with respect to kinetic parameters and inhibition of binding by nonradioactive GABA, before and after detergent treatment, suggest the presence of at least two types of binding at putative GABA receptor sites. |
