This track shows expression data from the GNF Gene Expression Atlas 2. This contains two replicates each of 61 mouse tissues run over Affymetrix microarrays. In full mode all tissues are displayed. In packed or dense mode averages of related tissues are shown. As is standard with microarray data red indicates overexpression in the tissue, and green indicates underexpression. You may want to view gene expression with the Gene Sorter as well as the Genome Browser.
