The invention provides compositions and methods for improved hybridization analysis utilizing DNA, RNA, PNA and chimeric oligomers in which one or more purine bases are substituted by a pyrazolo[5,4-d]pyrimidine or by a 7-deazapurine purine analogue. Reduced self-aggregation and reduced fluorescence quenching are obtained when the oligomers are used in various methods involving hybridization. Methods of synthesis, as well as novel synthetic precursors, are also provided.
本发明提供了一种利用DNA、RNA、PNA和嵌合寡核苷酸进行改进的杂交分析的组合物和方法,其中一个或多个嘌呤碱基被嘧唑并[5,4-d]嘧啶或7-脱氧嘌呤嘌呤类似物所替代。当这些寡核苷酸用于涉及杂交的各种方法时,可以获得减少自身聚集和减少荧光淬灭的效果。本发明还提供了合成方法以及新的合成前体。
