ØMicroarray technology allow one to identify the genes that are expressed in different cell types, to learn how their expression levels change in different
developmental stages or disease states, and to identify the cellular processes
in which they participate
ØMicroarray technology provide clues about how genes and gene products interact and their
interaction networks.

Microarray Slide
A microarray
experiment. The top part of the figure shows steps in the sample preparation
process while the bottom part shows steps in the fabrication of the
microarray. The samples are hybridized to the microarrays (center). The net
result of this complex multi-step procedure is increased understanding of the
effects of chemical toxicants.
