Membrane dopamine D1 receptor (D1R) expression in rat renal proximal tubules. A representative dose response curve of D1R antagonist [3H]SCH23390 in proximal tubule membranes (A). Bmax and Kd obtained from Scatchard plot (B and C). Experiments were performed in triplicate and data represents Mean ± SE from 5–7 rats in each group. *P<0.05 vs C and #P<0.05 vs BSO.
