概括

这就是Illumina Illumina.

科学领域:

基因组学就是基因组学.
病毒学病毒学
生物信息学是一种生物信息学.

背景情况:

Illumina 的 MiSeq 和 iSeq 是常见的下一代测序 (NGS) 平台.
MiSeq提供中等范围的吞吐量,而iSeq则以更低的成本提供更低的吞吐量.
关于这些病毒测序平台之间的直接质量比较数据有限.

研究的目的:

为了比较Illumina MiSeq和iSeq平台的测序质量.
为了评估SARS-CoV-2,诺病毒和脊髓灰质炎病毒基因组测序的性能.
为了评估读取质量,SNP调用和组装指标的差异.

主要方法:

在MiSeq和iSeq平台上对病毒样本 (SARS-CoV-2,诺病毒,脊髓灰质炎病毒) 进行测序.
分析修剪的读数质量指标 (例如,% ≥ Q30) 和参考映射.
评估单核酸多态性 (SNP) 协同性和基因组组装指标 (N50,最大连接长度).

主要成果:

两个平台都显示了同等的修剪读取质量 (% ≥ Q30) 和参考映射百分比.
观察到高SNP一致率:SARS-CoV-2的95.3%,诺罗病毒的99.7%,小儿麻病毒的81.8%.
在所有测试的病毒中,MiSeq和iSeq产生了可比的基因组组装指标 (N50,最大结合长度).

结论:

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Next-generation Sequencing

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features....

Sanger Sequencing

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
