How do I find out the total number of B cell/antibody epitopes reported for an organism of interest? How do I then determine the number of linear versus conformational epitopes? – IEDB Solutions Center

In the 'Search' interface on the left side of the IEDB home page, click the Organism Finder under the Epitope Source section to enter the source organism of interest. You can select from list of common selections (click on the selection and hit Apply Selection).
If your organism is not in the list, type the genus/species under Find (Use NCBI taxonomy) and hit 'Search.' The Finder will locate your entry within the taxonomy tree and it will be highlighted in blue. Click on this and once the organism appears in the Current Selection box at the top, click Apply Selection.
Back on the home page, go to the Immune Recognition Context section to exclude all but the B cell Response (check box) and then hit 'Search' at the bottom of the page. This will generate a set of Search Result Summary tables. This set of tables represents B cell epitope data only.
The Search Result Summary table automatically includes additional information, including assay, reference, epitope source and immunized host. Click on the values in blue to display further details of the data.
Results may include multiple pages and can be downloaded through the green Excel-based Export all results link.

SIMPLE SEARCH for linear or conformational B cell epitopes:

In order to specifically query for just the number of linear antibody epitopes, go back to the IEDB home page by hitting 'Revise Search.' Under Epitope Structure, use the radio button to select 'Linear Peptide' ('Any' is the default). Again, hit 'Search' at the bottom of the page.
This will generate a set of Search Result Summary tables that includes all reported linear B cell/antibody epitopes.
In order to specifically query for the number of discontinuous/conformational antibody epitopes, go back to the IEDB home page by hitting 'Revise Search.' Under Epitope Structure, use the radio button to select 'Discontinuous Peptide.' Again, hit 'Search' at the bottom of the page.
The Search Result Summary table automatically includes additional information, including assay, reference, epitope source and immunized host data.
Results may include multiple pages and can be downloaded through the green Excel-based Export all results link.
