  SEDB The SEDB describes the 3D-structure of epitope containing proteins and its interaction with protein. It also summarizes the source information, experimental details and additional related information of epitope such as methodology and detailed sequence information along with user convenient Jmol tool for epitope visualization.
URL: http://sedb.bicpu.edu.in 
It contains all the structure of TCR, MHC, and BCR complexes available in PDB, with emphasis on the structural characterization of these complexes.  Additionally, It also includes Ramachandran Plot, DIMPLOT, and Methodology and Gene Ontology information. Reference in details and the Assay information. It complements other existing specialized 3D epitope databases. B-Cell - 271

It locates the CDRs in the known protein–antibody complexes through the knowledge-based approach Ag    - 142
Extracted from protein–Ab complex structures
Structural information of protein, Rama-chandran plot, Gene Ontology, Sequence information, Developed for only B-Cell epitope. Not updated from long back.
  IEDB-3D IEDB-3D is fully embedded within IEDB, thus allowing structural data, both curated and calculated, and all accompanying information to be queried using multiple search interfaces.
URL: http://www.iedb.org
IEDB-3D include experiments describing recognition of epitopes or Ag (peptidic or nonpeptidic) by TCRs (T-cell assays describing 3D structures of antigens /epitopes in complexes with MHC and TCR),  immunoglobulin or antibodies (B-cell assays describing structures of Ab–Ag complexes), and MHC molecules B-Cell  - 270

MHC     -222
Extracted from the Protein Data Bank (PDB) and articles published in peer review journals.
Structural information of protein. , Rama-chandran plot, Gene Ontology, and the DIMPLOT for the interaction data.
  IMGT/3D IMGT/3Dstructure-DB provides the closest genes and alleles that are expressed in the AA sequences of the 3D structures, by aligning these sequences with the IMGT domain reference directory.
URL:www.imgt.org/IMGTindex/IMGT3Dstructure-db.html
IMGT/3Dstructure-DB contains 3D structures of  (1) AgR that comprise Ig or Ab and T CR, (2) MHC proteins of class I and class II, (3) peptide/MH (pMH) complexes (pMH1, pMH2), (4) AgR/Ag complexes (IG/Ag, TR/pMH), and (5) related proteins of the immune system (RPI) All entries in this database are manually curated from articles published in peer review journals. Structural information of  protein, Rama- chandran plot,  Gene Ontology, Sequence information
  CED CED has been developed as an information resource for investigators involved in both theoretical and applied immunology research.
