摘要：
To get a further understanding of protein adsorption onto ion-exchange chromatographic media, the binary adsorption of serum albumin and hemoglobin onto Q Sepharose FF was investigated with molecular dynamics (MD) simulations. Considering the adsorption sequence, both simultaneous and sequential adsorption has been simulated. The protein underwent a competing adsorption. The results show that serum albumin is preferentially adsorbed. A multi-layer adsorption was observed in the sequential binary simulations. Hence, this study provides a detailed description of protein adsorption on a molecular scale.
