基因转录水平的研究是功能基因组学和医学研究的基础。数字基因表达谱升级版(RNA-Seq)是用来研究某一生物对象在特定生物过程中基因表达差异的技术。该技术结合了转录组测序建库的实验方法与数字基因表达谱(Digital Gene Expression Tag Profiling, DGE)的信息分析手段,可广泛应用于生理调控、农业性状、生物标记、环境改造、疾病机制和药物筛选等领域。
针对RNA样本,采用电泳、NanoDrop、Agilent Bioanalyzer等方法进行样品检测。样本必须符合数字基因表达谱升级版建库要求。构建完成的文库,采用Agilent 2100检测浓度和片段长度,并用QPCR检测文库分子浓度。文库片段大小,浓度必须符合上机标准。
一、标准信息分析
1)测序评估(包括:数据比对统计、测序质量评估、测序饱和度分析、测序随机性分析、Reads在参考基因/基因组上的分布);
2)基因表达注释(包括:基因覆盖度统计、结果文件列表、结果文件示例);
3)条件特异表达分析(Proton平台,包括:条件特异表达基因统计图、样品特异基因结果);
4)主成分(PCA)分析(Proton平台);
5)差异表达基因筛选(包括:差异基因统计图、差异基因表达图、所有基因表达差异结果、差异表达基因筛选结果);
6)基因表达模式聚类分析;
7)Gene Ontology功能显著性富集分析;
8)Gene Ontology功能分类;
9)KEGG Pathway显著性富集分析;
10)蛋白互作网络分析。
二、定制化信息分析
可结合客户的需求,协商确定定制化信息分析内容。
Hiseq测序平台是研究表达谱强有力的工具,其具有高特异性和准确性,可很好满足客户的要求。
Proton测序平台是最新一代的测序技术,产品执行周期短,平均读长长,适合对项目执行周期要求高,或者对Proton测序平台感知度高的客户。
