DNA library preparation is a common entry point and bottleneck for next-generation sequencing. Current methods generally consist of distinct steps that often involve significant sample loss and hands-on time: DNA fragmentation, end-polishing, and adaptor-ligation. In vitro transposition with Nextera™ Transposomes simultaneously fragments and covalently tags the target DNA, thereby combining these three distinct steps into a single reaction. Platform-specific sequencing adaptors can be added, and the sample can be enriched and bar-coded using limited-cycle PCR to prepare di-tagged DNA fragment libraries. Nextera technology offers a streamlined, efficient, and high-throughput method for generating bar-coded libraries compatible with multiple next-generation sequencing platforms.
DNA文库制备是新一代测序的常见起始步骤和瓶颈。当前方法通常由不同步骤组成,这些步骤往往会导致大量样本损失和较长的人工操作时间:DNA片段化、末端抛光和接头连接。使用Nextera™转座体进行体外转座可同时对目标DNA进行片段化和共价标记,从而将这三个不同步骤合并为一个反应。可以添加特定平台的测序接头,并使用有限循环PCR对样本进行富集和条形码标记,以制备双标签DNA片段文库。Nextera技术提供了一种简化、高效且高通量的方法,用于生成与多个新一代测序平台兼容的条形码文库。
