Integrating probe-level expression changes across generations of Affymetrix arrays
There is an urgent need for bioinformatic methods that allow integrative analysis of multiple microarray data sets. While previous studies have mainly concentrated on reproducibility of gene expression levels within or between different platforms, we propose a novel meta-analytic method that takes into account the vast amount of available probe-level information to combine the expression change...
متن کاملExpression profiling using affymetrix genechip probe arrays.
Large-scale microarray expression profiling studies have helped us to understand basic biological processes and to classify and predict the prognosis of cancers; they have also accelerated the identification of new drug targets. Affymetrix GeneChip probe arrays are high-density oligonucleotide microarrays that are available for many prokaryotic and eukaryotic species. Affymetrix human and mouse...
متن کاملProbe Selection and Expression Index Computation of Affymetrix Exon Arrays
BACKGROUND There is great current interest in developing microarray platforms for measuring mRNA abundance at both gene level and exon level. The Affymetrix Exon Array is a new high-density gene expression microarray platform, with over six million probes targeting all annotated and predicted exons in a genome. An important question for the analysis of exon array data is how to compute overall ...
متن کاملPLANdbAffy: probe-level annotation database for Affymetrix expression microarrays
Standard Affymetrix technology evaluates gene expression by measuring the intensity of mRNA hybridization with a panel of the 25-mer oligonucleotide probes, and summarizing the probe signal intensities by a robust average method. However, in many cases, signal intensity of the probe does not correlate with gene expression. This could be due to the hybridization of the probe to a transcript of a...
متن کاملSummaries of Affymetrix GeneChip probe level data.
High density oligonucleotide array technology is widely used in many areas of biomedical research for quantitative and highly parallel measurements of gene expression. Affymetrix GeneChip arrays are the most popular. In this technology each gene is typically represented by a set of 11-20 pairs of probes. In order to obtain expression measures it is necessary to summarize the probe level data. U...
