适配子是一种高亲和力的寡核苷酸,可以通过指数富集法(SELEX)从大的随机文库中选择配体,具有与抗体相当或更好的亲和力和特异性。SELEX协议包括多轮选择,每轮选择都需要结合配体的再生,而结合配体的再生又需要随机文库区域两侧的固定引物序列。这些固定的引物序列可能会干扰(假阳性和假阴性)选择过程。在这里,我们提出了一种使用随机DNA文库的无引物检测方法。
Aptamers are high-affinity oligonucleotides which can be selected from large random libraries by systematic evolution of ligands by exponential enrichment (SELEX) protocols, with affinities and specificities comparable or better than antibodies. The SELEX protocols comprise multiple rounds of selection, each of which require regeneration of bound ligands, which in turn require fixed primer sequences flanking the random library regions. These fixed primer sequences can interfere (with false positives and negatives) with the selection process. Here we present a primer-free protocol using a random DNA library.
