摘要: 以随机寡核苷酸序列为文库,通过指数富集配体系统进化技术(systematic evolution of ligands by exponential enrichment, SELEX)能够获得与靶标特异性结合的核酸适体,这是一类新型的分子识别探针,其与靶标的亲和力可以同抗原抗体相媲美,甚至优于抗原抗体的结合。核酸适体广泛应用在生化分析、疾病诊断、药物研发等领域。本文将介绍核酸适体的筛选和特点,以及核酸适体在生物分子检测,疾病的诊断和治疗中的应用,最后介绍核酸适体在神经系统疾病研究中的应用。

Abstract: Aptamer, a specific oligonucleotide molecular obtained by systematic evolution of ligands by exponential enrichment (SELEX) , is a new class of molecular recognition element. It can specifically bind to target molecules. The affinity between target substance and matching aptamer is comparable with antigen-antibody binding. Multiple analysis and testing technologies based on the aptamer have been established, and widely applied in many fields including biochemical analysis, disease diagnosis, drug discovery and so on. Here, we will introduce the screening and characters of aptamer and the application in the area of biological molecular detection, disease biomarker. Finally, the application of aptamer on the research of nervous system diseases will be discussed.

Key words: aptamer, systematic evolution of ligands by exponential nrichment (SELEX), biochemical detection, disease diagnosis, nervous system disease
