重叠延伸PCR生成长重复DNA序列及其在纳米孔测序中的应用
Overlap-Extension PCR Generating Long Repetitive DNA Sequence and Its Application in Nanopore Sequencing
摘要
Abstract
Nanopore sequencing of short DNA fragments suffers from low pore utilization and poor data quality.It is urgent to establish a method of obtaining the sequence of short DNA fragments.In this study,PCR was performed at constant 72 ℃ using 1 nmol/L fully complementary primers and short DNA fragments as the template.The overlapping extension of short DNA fragments ultimately generated long tandem repeats,5~20 times longer than the original.The long DNA constructs can be sequenced directly with the accurate original sequence obtained simply by aligning only a few reads.The developed overlap-extension method improved the one read accuracy of nanopore sequencing to 99.28%,which plays an important role in improving the accuracy of nanopore sequencing.关键词
