What is gene expression analysis?
The use of Affymetrix GeneChips® allows for the simultaneous differential analysis of over 30,000 unique transcripts between distinct biological samples. Gene expression analysis by microarray refers to the analytical process whereby nucleic acids from experimental samples are labeled and hybridized with small DNA fragments printed on quartz microarray chips, followed by imaging of the microarray, normalization and statistical analysis of the resulting data. An in-depth discussion of gene expression is provided in the technology overview section of the Affymetrix web site.
