Kimerer, L.; Pabst, T.; Hunter, A.; Carta, G.: Role of configurational flexibility on the adsorption kinetics of bivalent bispecific antibodies on porous cation exchange resins, Journal of Chromatography A 1655 (2021): 462479.
The authors propose a new binding model with multiple bound states and interconversion kinetics that is similar but not identical to the multi-state SMA model.
