解析 答:NGS是一种高通量、高效、自动化的DNA测序技术。它通过将DNA样品分解成小片段,后续使用特定引物使得DNA-聚合酶对每个小片段进行复制,并附着在纳米孔上,通过插入等原理,将公司特异的测序扩增,经过显微镜下图像传感器的观察,得到数据并进行测量。反馈 收藏 ...
随着科学技术的发展,第一代测序技术已不能满足目前全基因组测序的需求,因此出现了现在的新一代基因测序方法,即NGS技术,又称大规模平行测序或深度测序,包括第二代、第三代和第四代测序技术。目前,具有代表性的第二代测序平台有基因组测序仪、HiSeq2000和MiSeq、寡聚物连接检测测序(sequencingbyoligoligationdetection...
Next-generation sequencing (NGS) is a technology for determining the sequence of DNA or RNA to study genetic variation associated with diseases or other biological phenomena. Introduced for commercial use in 2005, this method was initially...

血液肿瘤是一类具有高度异质性的疾病,其诊疗需要结合形态学、免疫学、遗传学和分子生物学进行综合分析。NGS作为新的分子生物学技术,具有通量高、灵敏度高、成本低等优势,是探索血液肿瘤的分子发病机制并指导临床诊疗的重要手段。为推动NGS在血液肿瘤诊疗中的应用,提高诊疗水平,中国抗癌协会血液肿瘤专业委员会、中华医学会...
2020年6月燃石、泛生子陆续在纳斯达克上市,成为中国肿瘤二代测序(next-generation sequencing, NGS)的第一批上市公司。本文尝试讨论NGS技术给行业可能带来的新变化。 一、NGS是什么?为什么认为它是具有“颠覆性”的技术? 1、什么是二代测序(NGS)?为什么称为二代测序呢?
- Roche 454 sequencing - Ion torrent: Proton / PGM sequencing - SOLiD sequencing 2.原理 此处主要介绍Illumina 平台的工作原理。 从本质上而言,二代测序(NGS)和Sanger测序相同,都是在每一个测序周期中,利用计算机检测DNA聚合酶催化荧光标记的dNTP结合到DNA模板时产生的荧光信号。但与Sanger单位时间检测单片段不...
高通量测序技术(Next Generation Sequencing, NGS)的相关数据一般是从3个类型的数据进行分析。分别是: 使用全基因组测序(Whole Genome Sequencing, WGS)进行点突变(SNP/SNV)与结构变异(CNV)的分析;使用RNA…
