Monoclonal antibodies and cell surface antigens
Ciba Foundation Symposium
|June 27, 1979
Summary
Researchers developed a method to create permanent cell lines producing specific antibodies. This technique involves fusing spleen cells with myeloma cells, enabling the production of monoclonal antibodies for complex antigens.
Area of Science:
- Immunology
- Molecular Biology
- Cell Biology
Background:
- Antibody chains are encoded by gene clusters with variable (V) and constant (C) regions.
- V and C genes rearrange during differentiation but remain non-contiguous, requiring RNA splicing for functional antibody mRNA.
Purpose of the Study:
- To establish permanent cell lines for producing antibodies of predefined specificity.
- To explore the potential of cell fusion for generating monoclonal antibodies against complex antigens.
Main Methods:
- Cell fusion techniques, specifically fusing antibody-producing spleen cells with myeloma cells.
- Cloning and propagation of hybrid cell lines.
- Analysis of antibody production in fused cell lines.
Main Results:
- Established permanent hybrid cell lines that synthesize and secrete specific antibodies.
- Demonstrated that cell fusion is a potent method for producing monospecific antibodies.
- Successfully produced monoclonal xenogeneic antibodies against rat, mouse, and human cell-surface antigens.
Conclusions:
- Hybridoma technology provides a powerful approach for generating monoclonal antibodies.
- These antibodies are valuable tools for characterizing cell surface antigens and differentiating cell subpopulations.
- This method facilitates the study of cell differentiation and immune responses.
