A. Adsorption isotherms (open designators) and desorption isotherms (solid designators) (500 mM NaCl) for different PVPA concentrations after they were immobilized to demineralized collagen matrices cross-linked with EDC only (circles), EDC/N-hydroxysuccinimide (NHS; squares) and EDC/imidazole (Im; triangles) at 37°C. Each point represents the mean of triplicate assays. B. Scatchard plots corresponding to the isotherms in Fig. 2A.
