The introduction of microarray technology has dramatically changed the way that researchers address many biomedical questions. DNA microarrays can measure expression of thousands of genes simultaneously, providing extensive information on gene interaction and function. Microarray technology is a powerful tool for identifying novel molecular drug targets and for elucidating mechanisms of drug action. Furthermore, microarrays can monitor the global profile of gene expression in response to specific pharmacologic agents, providing information on drug efficacy and toxicity. Over the last several years, dramatic advancements have occurred in array technology. In this review we describe basic aspects of microarray instrumentation and experimentation. Each of the major array formats including oligonucleotides arrays, spotted arrays, and macroarrays are examined, and advantages and options for using each format are presented. Important factors in the design and analysis of microarray experiments are also discussed. Most importantly, we explore recent developments in microarray technology that are relevant to pharmacogenomics and the discovery of gene function.
