Abstract

We designed a new type of pyrene-labeled base-discrimination fluorescent (BDF) nucleosides (Py)U, (Py)C, (8Py)A and (MePy)dA, which emitted strong fluorescence only when the bases opposite the BDF base are A, G, T and C, respectively. The DNA probes containing four different BDF bases enable us to distinguish single base alterations by simply mixing with a sample solution of target DNA.

摘要

我们设计了一种新型的芘标记的碱基识别荧光（BDF）核苷（Py）U、（Py）C、（8Py）A和（MePy）dA，它们仅在与BDF碱基相对的碱基分别为A、G、T和C时才发出强烈荧光。含有四种不同BDF碱基的DNA探针使我们能够通过与靶DNA样品溶液简单混合来区分单碱基改变。
