Saturation binding of [3H]DHA to membranes prepared from HEK 293 cells cultured in 10% FBS and infected with AAV-β2AR/EGFP. Membranes were incubated at 30°C for 20 minutes with increasing concentrations of [3H]DHA. Non-specific binding was defined with 0.1 μM (-)-propranolol. Inset: Direct plot showing total binding (closed circles), nonspecific binding (closed triangles), and specific binding (open circles). These data were representative of four separate experiments.
