Abstract

A new method for amplifying cDNA ends is described which requires only first-strand cDNA synthesis and a single PCR to generate a correct product with very low or no background. The method can be successfully applied to total RNA as well as poly A+ RNA. The same first-strand cDNA can be used to amplify flanking sequences of any cDNA species present in the sample.

摘要

本文描述了一种用于扩增cDNA末端的新方法,该方法仅需进行第一链cDNA合成和一次PCR,即可产生背景极低或无背景的正确产物。该方法可成功应用于总RNA以及聚腺苷酸RNA。相同的第一链cDNA可用于扩增样品中存在的任何cDNA物种的侧翼序列。
