The International ImMunoGeneTics information system (IMGT) provides standardized immunogenetics data and tools. IMGT ensures accuracy for immunoglobulin and T cell receptor analysis, aiding antibody engineering.
Area of Science:
- Immunogenetics
- Immunoinformatics
- Structural Biology
Background:
- IMGT is the global reference for immunogenetics and immunoinformatics.
- IMGT ensures data accuracy and consistency through IMGT-ONTOLOGY, linking genes, sequences, and 3D structures.
- IMGT applies standardized rules and nomenclature across different molecule types and species.
Purpose of the Study:
- To present the IMGT tools and databases for standardized analysis of immunoglobulin (IG) and T cell receptor (TR) V and C domains.
- To highlight the capabilities of IMGT/V-QUEST, IMGT/HighV-QUEST, IMGT/DomainGapAlign, and IMGT/3Dstructure-DB.
- To emphasize the utility of IMGT resources for antibody engineering and humanization.
Main Methods:
- IMGT/V-QUEST for V domain analysis of IG/TR rearranged sequences, integrating IMGT/JunctionAnalysis and IMGT/Automat.
- IMGT/HighV-QUEST for high-throughput sequencing data analysis with statistical capabilities.
- IMGT/DomainGapAlign for V and C domain amino acid sequence analysis and IMGT/3Dstructure-DB for 3D structure and interaction analysis.
Main Results:
- IMGT provides highly standardized analysis of IG and TR V and C domains.
- IMGT/HighV-QUEST enables high-throughput analysis of up to 150,000 sequences per batch.
- IMGT/3Dstructure-DB and associated tools offer insights into 3D structures and paratope/epitope interactions.
Conclusions:
- IMGT tools and databases are invaluable for antibody engineering and humanization.
- IMGT's standardized approach ensures high-quality data and analysis.
- IMGT/mAb-DB provides access to therapeutic antibody data, further supporting antibody development.

Antibody Structure
Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
