Figure 8From: Nucleoside conjugates of quantum dots for characterization of G protein-coupled receptors: strategies for immobilizing A2A adenosine receptor agonistsGeneral design features of QD conjugate 13, which bound with submicromolar affinity to the A 2A AR. The QD is represented here as a small sphere, but its diameter is approx. 6 nm, which is several times larger than the size of the appended dendron.Back to article page
