Abstract

To get a comprehensive understanding of the adsorption of macromolecules onto ion-exchange adsorbent, the single component ion-exchange adsorptions of serum albumin and hemoglobin onto Q Sepharose FF were investigated with both adsorption equilibrium experiments and molecular dynamics (MD) simulations. Both of the investigations show that serum albumin adsorbs stronger than hemoglobin in the condition studied. The steric mass-action model ...
