base-discriminating fluorescent (BDF) nucleoside, 8-fluorescence-labeled adenosine derivative (8PyA), was developed for the detection of thymine base on a target DNA. The BDF nucleoside was incorporated into oligodeoxynucleotides by post-synthetic modification. BDF probes containing 8PyA selectively emit fluorescence only when the base opposite BDF nucleoside is thymine and act as effective reporter probes
开发了新型的区分碱基的荧光(BDF)核苷,即8-荧光标记的腺苷衍生物(8Py A),用于检测靶DNA上的胸腺嘧啶。通过后合成修饰将BDF核苷掺入寡脱氧核苷酸中。包含8Py A的BDF探针仅在与BDF核苷相对的碱基为胸腺嘧啶时才选择性发出荧光,并充当均质SNP分型的有效报告探针。
