摘要
cDNA末端扩增技术是一种以PCR反应为基础,快速获得已知cDNA序列3′端和5′端的方法,是克隆全长cDNA序列的主要手段之一。本文从RACE原理出发,对RACE技术3个关键步骤(反转录、TdT加尾、PCR扩增)的优化和改良措施进行了透彻分析,并详细阐述RACE的最新研究进展———“电子”cDNA克隆。
Rapid amplification of cDNA ends is a method obtaining 3' ends and 5' ends of known cDNA fragments based on PCR reaction, and one of the primary means cloning cDNA fragments. Beginning with the principle this article analyses the three critical steps (transcription, TdT tailing, PCR amplification) of RACE technique in detail, and expatiates the latest RACE techniques (Marathon - PCR, SMART - RACE, In silico cloning).
