Genes showing similar expression profiles across differing states are likely to participate in common physiological or metabolic pathways. Cluster analysis programs have been developed which allow detection of co-expressed groups of genes reflecting information on function. The Functional Genomics Lab is equipped with a Cartesian Technologies microarrayer capable of spotting 50 slides per run, a GSI Lumonics ScanArray 3000 two color confocal laser scanner and image analysis software for data collection and analysis. The integration of the lab with the sequencing and bioinformatics units will provide the tools necessary for identification of genes that can be of practical value to the agriculture and healthcare communities. Scan of a hybridized soybean EST microarray.
Differential expression is shown as differences in color intensity.
This array represents 768 expressed genes isolated from soybean root and cotyledon cDNA libraries. All genes were spotted in duplicate. Spot size is approximately 150 micron with a 500 micron distance between spots. To inquire about fees for microarrays, please contact Mark Band , Director.
