Figure 2 (IMAGE) Kanazawa University Caption Repetitive binding of AgTx2 to potassium channel KcsA and AgTx2 - concentration dependence of binding probability. A. Time-lapse images of AgTx2 binding to and dissociation from the KcsA channels and time courses of the average height (h) (nm) around the center of the extracellular surface. Scale bar in the HS-AFM image, 5 nm. B. Height histograms of h depending on AgTx2 concentration in the solution.
