Gene expression microarrays

Molecular biology and genetics have advanced a lot in recent years, thanks to technological advances in this field. Now, the focus in genomic research is shifting from "structural genomics" (sequencing) towards "functional genomics" (using the sequences to understand gene function). The author discusses the principle of the microarray technique, target labelling and hybridization, data analysis and management, unsupervised and supervised analysis, application of microarrays and their future, cancer research and toxicology.
