Reversible self-association of a monoclonal antibody (MAb) in a high concentration formulation results in a solution with a high viscosity. The nature of the self-association of full-length as well as antibody fragments has been studied by rheometry. Chaotropic anions reduced solution viscosity more
The viscosity profiles of four different IgG 1 molecules were studied as a function of concentration at pH 6.0. At high concentrations, MAb-H and -A showed significantly higher viscosities as compared to MAb-G and -E. Zeta Potential (j) measurements showed that all the IgG 1 molecules carried a net
