BioDynami PCR-Free NGS DNA建库试剂盒——illumina平台
产品简介:
BioDynami PCR-Free NGS DNA建库试剂盒,用于二代测序的DNA文库(illumina平台)。该试剂盒有效地将3 ' -dT-tailed库适配器添加到DNA片段的两端。该试剂盒使用双链DNA片段(钝性和/或粘性)作为NGS文库构建的输入DNA,并与酶促法(BioDynami DNA片段酶等)和物理法(超声、雾化等)产生的DNA片段兼容。

BioDynami PCR-Free NGS DNA建库试剂盒工作流程
PCR扩增是二代测序文库制备的标准步骤。PCR用于扩增完全连接的DNA片段并为文库添加index信息。index是为了汇集库样本,以减少测序成本。然而,PCR在一些GC含量和二级结构极高的DNA区域引入了不均匀扩增的DNA。这种偏倚可能导致这些地区的测序覆盖率非常低。这些区域的DNA测序仍然是一个巨大的挑战。PCR-Free NGS DNA建库可以减少文库偏倚并最小化测序缺口。来自PCR-free文库样本的测序数据甚至具有基因组覆盖,几乎没有空白区和更好的GC丰富区域深度。BioDynami PCR-Free NGS DNA建库试剂盒可以在传统上比较困难的区域提供最佳覆盖,例如高GC含量区域,低GC含量区域和重复序列区域。
The PCR-free NGS DNA Library Prep Kit was developed for construction of DNA libraries for next generation sequencing (illumina platform). The kit adds 3′-dT-tailed library adapters to both ends of DNA fragments efficiently. The kit uses double strand DNA fragments (blunt and/or sticky) as input DNA for NGS library construction, and is compatible with DNA fragments generated from both enzymatic methods (BioDynami DNA fragmentation enzymes etc.) and physical methods (sonication, nebulization etc.).PCR amplification is a standard step for library preparation of Next-Generation Sequencing. The PCR is used to amplify fully ligated DNA fragments and to add index information to the libraries. The indexing is for the pooling of the library samples in an effort to reduce the sequencing cost.However, PCR introduces uneven amplification of DNA in some DNA regions with extreme GC-contents and secondary structures. This bias can cause very low sequencing coverage in such regions. DNA sequencing in these regions is still a huge challenge.PCR-free library prep can reduce library bias and minimize sequencing gaps. The sequencing data from PCR-free library samples have even genomic coverage with few gaps and better depth in GC-rich regions. Our PCR-free NGS kit offers optimal coverage in the regions that are traditionally difficult, such as high-GC content regions, low-GC content regions, and repetitive sequence regions.
试剂盒有两种index类型:
Non-index:库没有索引。
Index:每个库包含一个i5索引和一个i7索引。库复用可多达96个样本。
产品优势:
★ 总时间:1小时;
★ 操作时间:5分钟;
★ 简单的程序:准备使用的主混合和较少的反应试剂盒;
★ DNA输入量从100微克到1微克。
什么是基因组:
基因组(genome)是细胞或生物体的全套遗传物质,或载有遗传信息的全体核酸,包括所有染色体上的核酸。各种生物体之间存在着差异,这种差异正是由基因组所决定的。基因组控制着生物体的生长发育和生命活动。近几年二代测序技术迅速发展,广泛用于各种 DNA 研究,尤其对基因组学研究起到了巨大的推动作用。通过测序对序列进行拼接组装,比对分析,最终对研究物种进行全面解读,有助于后续研究该物种的生长、发育、进化、起源等问题,并为后续的基因挖掘、功能验证提供 DNA 序列信息。
传统建库流程主要分为以下几个步骤:
(1)将待测序的DNA分子用超声波打碎成200-500bp长的序列片段
(2)将打碎后的基因组进行末端补平
(3)在补平后的片段3’端加A和5’端进行磷酸化
(4)对修复后的片段进行接头连接
(5)对接头连接后DNA片段进行PCR扩增
(6)对扩增后的文库进行磁珠纯化
PCR-Free文库,顾名思义,就是在文库构建过程中不需要进行PCR的文库。主要是针对一些特殊样本,比如GC含量高、PCR扩增困难的样本和PCR产物。不足之处在于所需的样本起始量较少。
