Provided herein are methods and compositions for nucleic acid amplification. These methods involve the use of 3'-substituted nucleoside 5'-triphosphates or 3'-substituted terminated primers in nucleic acid amplification reactions. In certain aspects, the methods are accomplished by use of 3'-substituted NTPs and/or 3'-substituted terminated primers which provide utility in nucleic acid amplification. In preferred embodiments, the NTPs and/or primers are substituted at the 3'-position with particular heat labile chemical groups such as ethers, esters or carbonate esters.
本文提供了用于核酸扩增的方法和组合物。这些方法涉及在核酸扩增反应中使用3'-取代核苷酸5'-
三磷酸盐或3'-取代终止引物。在某些方面,这些方法通过使用3'-取代核苷酸
三磷酸盐和/或3'-取代终止引物来实现,这在核酸扩增中具有实用性。在优选实施例中,核苷酸
三磷酸盐和/或引物在3'-位置被特定的热不稳定
化学基团(如醚、酯或
碳酸酯)取代。
