3-alkynyl inosine analogs and their uses as universal bases are provided. The inosine analogues can be incorporated into nucleic acid primers and probes. They do not significantly destabilize nucleic acid duplexes. As a result, the novel nucleic acid primers and probes incorporating the inosine analogues can be used in a variety of methods. The analogs function unexpectedly well as universal bases. Not only do they stabilize duplexes substantially more than hypoxanthine opposite A, C, T, and G but they are also recognized in primers by polymerases, allowing efficient amplification.
提供了3-炔基
肌苷类似物及其作为通用碱基的用途。这些
肌苷类似物可以被纳入到核酸引物和探针中。它们不会显著破坏核酸双链。因此,纳入
肌苷类似物的新型核酸引物和探针可用于多种方法。这些类似物出乎意料地作为通用碱基表现出良好的功能。它们不仅可以显著稳定双链,而且还可以被聚合酶在引物中识别,从而实现高效扩增。
