Second-strand cDNA priming is a central problem for full-length characterization of transcripts. A new strategy using bacteriophage T4 DNA ligase and partially degenerate adapters is proposed for grafting a sequence tag to the end of polyribonucleotides. Based on this RNA tagging system and previously described protocols, a new method for full-length cDNA production has been implemented. Validation of the method is shown in Arabidopsis thaliana by the construction of a full-length cDNA library and the analysis of 154 clones and by 5'-RACE-PCR run on a documented experimental system.
第二链cDNA引发是转录本全长表征的核心问题。本文提出了一种使用噬菌体T4 DNA连接酶和部分简并衔接子的新策略,用于在多聚核糖核苷酸末端嫁接序列标签。基于此RNA标记系统和先前描述的方案,实现了一种全长cDNA制备的新方法。通过构建全长cDNA文库、分析154个克隆以及在一个有记录的实验系统上进行5'-RACE-PCR,在拟南芥中验证了该方法。
