Compositions and methods are provided for increasing the specificity of a probe nucleic acid for a target nucleic acid in a hybridization solution. An abasic residue, deoxyNebularine residue, or a hybotrope is used to increase specificity. A method is provided for identifying useful hybotropes, including salts, water miscible organic solvents, aprotic solvents and organic solvents, on the basis of enthalpy considerations. Hybotropic hybridization and modified oligonucleotides may be used in amplification reactions, such as PCR, sequence analysis methods, and genomic screening methods.
本文提供了提高杂交溶液中探针核酸对目标核酸特异性的组合物和方法。使用消旋残基、脱氧星云残基或同源物来提高特异性。本研究提供了一种方法,可根据焓的考虑来确定有用的同素异形体,包括盐类、水溶性有机溶剂、烷基溶剂和有机溶剂。杂交和修饰寡核苷酸可用于扩增反应,如 PCR、序列分析方法和基因组筛选方法。
