The protein adsorption isotherms (not shown here) for all these systems... 

Fig. 12. Hypothetical 3-D plot of protein adsorption isotherm (D plotted against [P]B) as a function of surface ligand concentration, [A]s. Note that the system is reversible only up to a critical [A]s and then behaves irreversibly for higher ligand surface concentrations. The right arrows (— ) denote adsorption the left-facing ones ( -), desorption...

Fig. 18 a. A schematic of kinetic overshoot adsorption data, as discussed by Soderquist and Walton 72), Van Dulm and Norde 65), and others. See text for explanations, b. The kink at about halfsaturation often observed in protein adsorption isotherms... 

Secondly, protein adsorption isotherms are often not Langmuirian but instead fit a Freundlich isotherm,... 

Although most of the protein adsorption isotherms studied here were constructed at moderate temperatures (18-27°C), the confinement made concerning the acceptable temperature range emanates fi om two points ...
