Ａｐｔａｍｅｒ指的是能结合蛋白或其他小分子物质的单链或双链寡核苷酸〔1〕 。体外筛选技术的发展和ＰＣＲ技术的应用 ,使得Ａｐｔａｍｅｒ的研究近年来有了长足的进步 ,筛选到了一大批能与各种蛋白或小分子特异紧密结合的核酸分子(Ａｐｔａｍｅｒ)。这些Ａｐｔａｍｅｒ包含 Aptamer refers to single- or double-stranded oligonucleotides that bind proteins or other small molecules [1]. The development of in vitro screening technology and the application of PCR technology have made Aptamer’s research progress in recent years and screened a large number of nucleic acid molecules (Aptamers) that can bind closely with various proteins or small molecules. These Aptamer contains
