Fig. 7. Long-term stability of β2AR solubilized in DDM, MNG-10,10, or an A-MNG (MNG-9,11, MNG-8,12, MNG-6,14, or MNG-4,16). The DDM-purified receptor was diluted into individual detergent-containing buffer solutions to give final detergent concentrations of CMCs + 0.2 wt%. The specific ligand binding ability of the receptor was measured using the radiolabeled antagonist ([3H]-dihydroalprenolol (DHA)) following 30-min dilution (0 h) and was further monitored at regular intervals during a 5-day incubation at room temperature. Error bars, SEM; n = 3.
