| 摘要 目的：为了验证不同高保真DNA聚合酶是否会对运用ARTIC工作流进行新型冠状病毒纳米孔测序产生影响。方法：使用英国Nanopore公司MinION测序仪对2份已获得全基因组序列的新冠肺炎确诊病例核酸样本分别采用KAPA HiFi HotStart ReadyMix，PrimeSTAR?誖GXL DNA Polymerase和NEBNext High-Fidelity 2X PCR Master Mix进行ARTIC工作流的多重PCR扩增，对扩增产物进行测序，并对测序质量进行分析。结果：不同高保真DNA聚合酶在相同扩增条件下，扩增产物的质检结果和测序质量均不相同，NEBNext High-Fidelity 2X PCR Master Mix在覆盖度和测序深度上明显好于另外两种酶。结论：NEBNext High-Fidelity 2X PCR Master Mix在纳米孔新型冠状病毒ARTIC快速测序工作流中的应用效果较好。 |

| ABSTRACT Objective: To verify whether the selection of different high-fidelity DNA polymerases has an impact on the results of nanopore sequencing of SARS-CoV-2 with ARTIC-nCoV network workflow. Methods: Multiplex PCR amplification of ARTIC-nCoV network workflow were performed on nucleic acid samples of two confirmed COVID-19 patients with KAPA HiFi HotStart ReadyMix, PrimeSTAR? GXL DNA Polymerase or NEBNext High-Fidelity 2X PCR Master Mix. The amplicons were sequenced on Nanopore MinION platform, then were analyzed. Results: Under same conditions, different high-fidelity DNA polymerases lead to different results of quality inspection and sequencing quality. NEBNext High-Fidelity 2X PCR Master Mix is the best among the three enzymes in coverage and sequencing depth. Conclusion: NEBNext High-Fidelity 2X PCR Master Mix has better effect in nanopore sequencing with ARTIC-nCoV network workflow. |
