Did you know?
Web在之前一期内容（走近NCBI（三）——GEO数据库，“生信分析”基础一）中我们介绍过如何利用GEO数据库内置分析工具（Analyze with GEO2R）筛选Expression profiling by array（其实就是microarray）上的差异表达基因。那么如何利用GEO数据库中的原始数据（raw data）自己分析呢？ WebArray based comparative genomic hybridization (array CGH) has emerged as a powerful tool for detecting gene copy number variants implicated in many disease states. Simple, robust genomic DNA labeling reagents and removal of free dye and nucleotides are two of the most critical components determining array CGH experiment’s performance.
WebMicroarrays provide the distinct advantage of assaying millions of distinct sequences in parallel which makes the technique immune to issues detecting and measuring low abundance transcripts, or rare alternative splicing events. For fast RNA expression analysis, we offer a complete range of arrays for whole-transcriptome, gene, exon, or … WebAffy芯片数据预处理，一般分为三个步骤. 1.背景处理（background adjustment）. 2.归一化处理（normalization）. 3.汇总（Summarization）. normalization 可以选择mas5，rma，gcrma等方法，一般后两个比较常用。. 可以根据自己的数据集情况自行选择。. 基因芯片数据处理当中不同 ...
WebDNA arrays have become the preferred method for large-scale expression measurement. Such data are needed in view of the large amounts of sequence data available: expression levels in a number of different tissues or situations provide a first step toward functional characterisation of new entities r … WebCluster analysis has placed a group of down regulated genes in the upper left corner. In the field of molecular biology, gene expression profiling is the measurement of the activity (the expression) of thousands of genes at once, to create a global picture of cellular function. These profiles can, for example, distinguish between cells that are ...
