Figure 1.

Binding of apt #1 to bPrP and bPrP-β. Binding curves of apt #1 to bPrP and bPrP-β are shown by closed circles and open circles, respectively. Solid and dashed lines represent different buffer conditions: 10 mM K⁺ and 100 mM Na⁺, respectively. The binding data are analyzed by GraphPad PRISM (see Materials and Methods).
