As a result, electrostatic interactions and hydrogen bond were identified to contribute to the affinity interaction, while hydrophobic interaction contributed little. Moreover, the importance of electrostatic interactions and hydrogen bond to the affinity changed with pH value.The effect of rate of mobile phase on the retention of insulin was researched and the dynamic adsorption isotherm was got by analyzing the breakthrough data with Langmuir equation.

通过调节流动相的pH值和离子强度，并使用尿素和乙二醇分别对吸附蛋白进行洗脱，详细研究了吸附效果最好的目标蛋白质与肽配基之间的亲和吸附机理，发现静电作用和氢键是二者之间产生亲和吸附的主要作用力，而疏水相互作用对该亲和几乎没有贡献。
