适配子(aptamer)是能够与靶分子以高亲和力、高特异性结合的相对短小的核酸或肽,大部分适配子通过“指数富集的配体系统进化”(SELEX)技术筛选而来。适配子可分为核 Aptamers are relatively short nucleic acids or peptides that bind to a target molecule with high affinity and high specificity, and most of the aptamers are screened by the “exponential enrichment ligand system evolution” (SELEX) technique Come. Aptamers can be divided into nuclei
