——TruSeq RNA文庫制備試劑盒v2 加樣量要求

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.

優(yōu)化加樣量:總RNA 0.1-1µg

RNA量低于0.1µg可能會影響連接效率導致產(chǎn)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.

也可以預先從總RNA分離得到mRNA作為起始樣本。從0.1-1µg總RNA分離的所有mRNA都要用于加樣。

 

——Illumina® TruSeq® RNA Sample Preparation Kit v2制備流程

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試劑將總RNA的mRNA轉(zhuǎn)化為模板文庫,以用于后續(xù)的DNA測序。

 

1. 純化:通過oligo-dT磁珠法純化得到poly-A mRNA分子。

 

2. mRNA 切段:高溫,二價陽離子。

3. mRNA 段子轉(zhuǎn)為*條cDNA:逆轉(zhuǎn)錄酶,隨機引物。

4. 第二條cDNA合成:DNA 聚合酶I ,RNase H。

 

5. cDNA 段子末端修復:添加A堿基,連接接頭。

 

6. 產(chǎn)物純化,PCR富集,得到cDNA文庫。

 

TruSeq® RNA Sample Preparation Kit v2文庫制備方法分為低樣品量和高樣品量兩種。

mRNA測序簡介

mRNA測序(mRNA-Seq)已迅速成為分析疾病狀況、生物過程及廣泛研究設計中的轉(zhuǎn)錄組的方法。mRNA-Seq不僅可提供極為準確且高靈敏度的量化基因表達,還可識別已知的和新的轉(zhuǎn)錄異構體、基因融合和其他特征及等位基因特異性表達。mRNA-Seq可提供編碼轉(zhuǎn)錄組的完整視圖,而并不受限于先驗知識。

mRNA測序的優(yōu)勢

與基因表達芯片相比,mRNA-Seq在分析轉(zhuǎn)錄組方面具有諸多優(yōu)勢:

該方法適用于更廣泛的動態(tài)范圍,不僅可增加靈敏度,還可提高基因表達中測量的倍數(shù)變化的準確性。

可捕獲已知特征和新發(fā)特征

可廣泛應用于眾多物種

用于癌癥研究的mRNA-Seq

 癌癥會積累大量的基因變化,但通常只有少數(shù)發(fā)展為腫瘤。借助mRNA-Seq監(jiān)控基因表達變化有助于識別疾病預后或治療反應的預測性生物標志物。mRNA-Seq還支持對基因表達和病因進行特征分析,并可了解影響腫瘤分類和發(fā)展的變異。

用于復雜疾病研究的基因表達圖譜

 基因表達圖譜和調(diào)控研究可讓您形象地了解基因組、表觀遺傳和環(huán)境因素對常見疾病的影響程度。mRNA-Seq是一種成熟的探查和圖譜分析工具,可提供具有較高影響力的研究結(jié)果,并識別針對一系列復雜疾病的下游調(diào)查的目標靶點,其中包括神經(jīng)系統(tǒng)、免疫系統(tǒng)、新陳代謝以及心血管方面的疾病。
