  1. 1. Electrostatic interaction chromatography : aspects of the salt dependent interactions of proteins

    Författare :Elisabeth Hallgren; Klaus Unger; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis studies the ionic strength dependence of protein retention in ion-exchange chromatography (IEC). It discusses some aspects of the use and applicability of retention models in describing the interaction between a protein and the highly charged stationary phase. LÄS MER
