Next-generation sequencing (NGS) is a powerful tool for genomic studies, translational research, and clinical diagnostics that enables the detection of single nucleotide polymorphisms, insertions and deletions, copy number variations, and other genetic variations. Target enrichment technologies improve the efficiency of NGS by only sequencing regions of interest, which reduces sequencing costs while increasing coverage of the selected targets. Here we present NEBNext Direct , a hybridization-based, target-enrichment approach that addresses many of the shortcomings of traditional target-enrichment methods. This approach features a simple, 7-hr workflow that uses enzymatic removal of off-target sequences to achieve a high specificity for regions of interest. Additionally, unique molecular identifiers are incorporated for the identification and filtering of PCR duplicates. The same protocol can be used across a wide range of input amounts, input types, and panel sizes, enabling NEBNext Direct to be broadly applicable across a wide variety of research and diagnostic needs. © 2017 by John Wiley & Sons, Inc.
新一代测序(NGS)是用于基因组研究、转化研究和临床诊断的强大工具,能够检测单核苷酸多态性、插入和缺失、拷贝数变异及其他遗传变异。靶向富集技术通过仅对感兴趣区域进行测序来提高NGS的效率,这在增加所选靶点覆盖范围的同时降低了测序成本。在此,我们介绍NEBNext Direct,一种基于杂交的靶向富集方法,它解决了传统靶向富集方法的许多缺点。该方法具有简单的7小时工作流程,利用酶促去除脱靶序列以实现对感兴趣区域的高特异性。此外,还引入了独特分子标识符用于鉴定和过滤PCR重复序列。相同的方案可用于广泛的输入量、输入类型和文库大小,使NEBNext Direct能够广泛适用于各种研究和诊断需求。© 2017约翰威立国际出版公司
