    • Methods are provided to label nucleic acids through two-step phosphoramidation reactions with regiospecificity and high sensitivity. The methods can be widely used for synthesizing conjugates of nucleic acids. Through the two-step phosphoramidation reactions, nucleic acids are directly or indirectly labeled for easier and more efficient applications. The present invention also uses fluorescence quenching and DNA melting profile studies to demonstrate that the nucleic acids modified through the two-step phosphoramidation reactions preserve intrinsic base-pairing specificity and bestow regioselectivity in nucleic acids with high yield. Thus, the present invention has significant contribution to basic nucleic acid research; and, in the future, can be applied to effectively and quantitatively detect and measure nucleic acids inside and outside living organisms.
    • 提供了通过具有区域特异性和高灵敏度的两步氨基磷酰化反应来标记核酸的方法。 该方法可广泛用于合成核酸的缀合物。 通过两步磷酰胺化反应,核酸被直接或间接标记,以便更容易和更有效的应用。 本发明还使用荧光猝灭和DNA熔解曲线研究来证明通过两步磷酰胺化反应修饰的核酸保持内在的碱基配对特异性并且以高产率赋予核酸的区域选择性。 因此,本发明对碱性核酸研究有重要贡献; 并且在未来可以应用于有效和定量地检测和测量生物体内外的核酸。
