——TruSeq RNA文库制备试剂盒v2 加样量要求
TruSeq RNA Sample Preparation v2 protocols are optimized for 0.1–1 µg of total RNA.Lower amounts of RNA might result in inefficient ligation and low yield.
优化加样量:总RNA 0.1-1µg
RNA量低于0.1µg可能会影响连接效率导致产量低。
You can also use previously isolated mRNA as starting material. Use the entire fraction of mRNA purified from 0.1–1 µg of total RNA.
也可以预先从总RNA分离得到mRNA作为起始样本。从0.1-1µg总RNA分离的所有mRNA都要用于加样。
——Illumina® TruSeq® RNA Sample Preparation Kit v2制备流程
This protocol explains how to convert the mRNA in total RNA into a library of template molecules suitable for subsequent cluster generation and DNA sequencing using the reagents provided in the Illumina® TruSeq® RNA Sample Preparation Kit v2.
The first step in the workflow involves purifying the poly-A containing mRNA molecules using oligo-dT attached magnetic beads. Following purification, the mRNA is fragmented into small pieces using divalent cations under elevated temperature. The cleaved RNA fragments are copied into first strand cDNA using reverse transcriptase and random primers. Second strand cDNA synthesis follows, using DNA Polymerase I and RNase H.
The cDNA fragments then go through an end repair process, the addition of a single ‘A’ base, and then ligation of the adapters. The products are then purified and enriched with PCR to create the final cDNA library.
流程概述:使用Illumina® TruSeq® RNA Sample Preparation Kit v2试剂将总RNA的mRNA转化为模板文库,以用于后续的DNA测序。
1. 纯化:通过oligo-dT磁珠法纯化得到poly-A mRNA分子。
2. mRNA 切段:高温,二价阳离子。
3. mRNA 段子转为*条cDNA:逆转录酶,随机引物。
4. 第二条cDNA合成:DNA 聚合酶I ,RNase H。
5. cDNA 段子末端修复:添加A碱基,连接接头。
6. 产物纯化,PCR富集,得到cDNA文库。

mRNA测序简介
mRNA测序(mRNA-Seq)已迅速成为分析疾病状况、生物过程及广泛研究设计中的转录组的方法。mRNA-Seq不仅可提供极为准确且高灵敏度的量化基因表达,还可识别已知的和新的转录异构体、基因融合和其他特征及等位基因特异性表达。mRNA-Seq可提供编码转录组的完整视图,而并不受限于先验知识。
mRNA测序的优势
与基因表达芯片相比,mRNA-Seq在分析转录组方面具有诸多优势:
该方法适用于更广泛的动态范围,不仅可增加灵敏度,还可提高基因表达中测量的倍数变化的准确性。
可捕获已知特征和新发特征
可广泛应用于众多物种
用于癌症研究的mRNA-Seq
癌症会积累大量的基因变化,但通常只有少数发展为肿瘤。借助mRNA-Seq监控基因表达变化有助于识别疾病预后或治疗反应的预测性生物标志物。mRNA-Seq还支持对基因表达和病因进行特征分析,并可了解影响肿瘤分类和发展的变异。
用于复杂疾病研究的基因表达图谱
基因表达图谱和调控研究可让您形象地了解基因组、表观遗传和环境因素对常见疾病的影响程度。mRNA-Seq是一种成熟的探查和图谱分析工具,可提供具有较高影响力的研究结果,并识别针对一系列复杂疾病的下游调查的目标靶点,其中包括神经系统、免疫系统、新陈代谢以及心血管方面的疾病。
