Expression Profiling Using Affymetrix GeneChip Microarrays.
The approximately 25,000 genes in mammalian genomes can be transcribed at different levels. Measurements of gene expression for ten thousands of genes in parallel give the most comprehensive picture of steady-state levels of transcripts and is used in basic and applied research. Microarrays are the most frequently used technology for genome-wide expression profiling; from the various available ...
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 کاملComparison of Affymetrix GeneChip expression measures
MOTIVATION In the Affymetrix GeneChip system, preprocessing occurs before one obtains expression level measurements. Because the number of competing preprocessing methods was large and growing we developed a benchmark to help users identify the best method for their application. A webtool was made available for developers to benchmark their procedures. At the time of writing over 50 methods had...
متن کاملA benchmark for Affymetrix GeneChip expression measures
MOTIVATION The defining feature of oligonucleotide expression arrays is the use of several probes to assay each targeted transcript. This is a bonanza for the statistical geneticist, who can create probeset summaries with specific characteristics. There are now several methods available for summarizing probe level data from the popular Affymetrix GeneChips, but it is difficult to identify the b...
متن کاملQualitative Assessment of Gene Expression in Affymetrix Genechip Arrays
Affymetrix Genechip microarrays are used widely to determine the simultaneous expression of genes in a given biological paradigm. Probes on the Genechip array are atomic entities which by definition are randomly distributed across the array and in turn govern the gene expression. In the present study, we make several interesting observations. We show that there is considerable correlation betwe...
