However, relatively lower column utilization limits its application to the complex proteome isolation. In case of binding biotin molecules to a specific kind of functional groups existed in protein structure, and flowing the digested peptides over the affinity column in which avidin has been immobilized, biotinylated peptides can be selectively separated and the complicated system is simplified.

因此根据需要，变换生物素试剂与蛋白质反应的作用位点，就可以选择性地分离出不同的目标肽段，从而大大提高亲和色谱柱的使用效率，降低亲和分离的成本；结合乙酰化同位素标记技术，还可以建立多种针对不同目标肽段的特色定量分析方法，ICAT即是将同位素标记与蛋白质巯基生物素化亲和分离成功结合的一个范例。
