Inhibition of [³H]GBC binding to SUR1 by OCoA in the absence and presence of MgATP (0.3 mM). Data are means from three to four experiments. Individual inhibition curves were analysed according to the Hill equation as described in Methods; the parameters are listed in Table 2. [³H]GBC concentration was ∼1 nM, B_S was ∼600 fmol mg⁻¹ and B_NS <10% B_TOT.
