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 microarray platforms, Affymetrix GeneChips are most frequently used for expression profiling and over
3,000 scientific publications describe results of this technology. In medical research, expression profiling by microarrays
holds great promises for better understanding of diseases, identification of new therapeutic targets, and subclassification
of diseases to identify individualized treatment strategies.
