Enter Query Structure

Note:
1) PDB structure of a protein antigen must be labeled with a single chain. The epitope residues can be specified in the following steps.
2) Batch files can be uploaded by adding new files.
3) Antigen-antibody complex should be preprocessed to retrieve the antigen structure before uploading.
4) You may find useful tools to preprocess your files (click here).

Example of processed conformational epitopes: 1J1O  2DQJ 

Enter Query Sequence

Note:
1) Multiple sequences can be included in one FASTA file.
2) CE-BLAST identifies a highly similar sequence to your query as a representative to search the HA1 database.
3) If your HA1 sequence is new, please model the structure first and then upload the structure from the track of Enter Query Structure.
