Figure 1.

Left: GXD assay details pages provide detailed annotations of experimental parameters and expression results. Shown is an example of an Assay Detail page for an immunohistochemistry experiment illustrating the detailed content of expression results in GXD. The Assay section reports the reference from which the data were derived, the assay type, the gene analyzed, and the antibody used, with links to more details about the antibody, reference, and gene. The Results section reports the tissue (Theiler stage and anatomical structure) analyzed, as well as the level and pattern of expression, as described by the authors. Images of the original expression data are displayed together with the corresponding annotations whenever possible. Major specimen details such as the age and mutant alleles are always displayed on this page. Other information, such as genetic background, sex, and specimen preparation method, is accessible via the ‘more’ toggle.

Right: Image detail pages are accessed by clicking on the image panes or pane labels shown in the assay details record. They show the entire figure, as published, providing the scientific context. As shown in the Associated Assays table of this example, several genes were studied in the same or similar tissue sections; the assay IDs and gene symbols link to the corresponding annotations for each image pane. While the image detail pages provide visual context, it is the detailed and standardized text annotations shown on the GXD assay detail pages (left) that make the expression data, including image data, accessible to searching.
