Cross-React: Prediction of allergen cross-reactivity

For cross-reactivity prediction, please select group of amino acids in epitope location, and upload a PDB file of interest. The server will use this information to search all allergenic protein structures listed in Structural database of allergenic protein, SDAP. Please do not upload a PDB complex. Use only one PDB chain name or a monomeric protein structure. You can use a PDB id or one word for your pdbfile name. Average processing time per query is ~90 sec.

Note: If you have a protein complex, then list of amino acids in IgE binding site can be calculated from or utility.
