Stimulation of [35S]-GTPγS binding by DAMGO and SNC80. SH-SY5Y membrane homogenates were incubated with 50 pM [35S]-GTPγS in the presence of DAMGO or SNC80 as described in Methods. The data are expressed as [35S]-GTPγS binding stimulation relative to the maximum effect produced by DAMGO. Data represent means±s.e.mean from at least three experiments carried out in duplicate.
