摘要: 核酸适配体亲和色谱是将核酸适配体作为色谱固定相上的亲和配体的一种新型色谱技术。核酸适配体是一种可以特异性地识别目标物的寡聚核苷酸,与免疫抗体相比,核酸适配体在筛选制备、稳定性及应用等方面都显示出独特的优点。本文介绍了核酸适配体亲和色谱在小分子、蛋白质和细胞的分离和分析中的应用,对核酸适配体亲和色谱的研究现状和发展前景进行了综述。

Abstract: Aptamer affinity chromatography makes the use of aptamers as affinity ligands to achieve chromatographic separation and concentration. Aptamers are single stranded oligonucleotides that can specifically bind to targets. They show unique advantages over antibodies in preparation, stability and applications. This article summarizes the applications of aptamer affinity chromatography to the separation and analysis of small molecules, proteins, and cells. By critically evaluating literature, this review describes the current status and discusses the future prospects of aptamer affinity chromatography.

Key words: affinity chromatography, cells, proteins, review , separation; detection, small molecules, aptamers
