Representation of the device used to measure the binding events. The Ni-NTA (labeled N) grafted slides containing the TR fixed through its 6×His N terminus (labeled H) to the glass and with the avidinated magnetic bead bound to its biotinylated C terminus (labeled B) was placed over the objective. Alexa 488–Vh was added to the slides for the period of the incubation. The TR and Vh structures are represented in green and yellow, respectively. The arrow shows the direction of the movement of the beads when they are pulled using the magnetic tweezers.
