## Contributions
César Milstein is most notably recognized for co-developing the hybridoma technique, a method that enables the production of large quantities of identical antibodies, known as monoclonal antibodies. This breakthrough, achieved in collaboration with Georges Köhler in 1975, involved fusing antibody-producing B cells with immortal myeloma cells to create hybrid cell lines capable of indefinite antibody production. The technique became foundational in biomedical research, diagnostics, and therapeutic development, including treatments for cancer, autoimmune diseases, and infectious diseases.

Milstein's work laid the groundwork for the biotechnology industry, particularly in the development of pharmaceuticals such as Herceptin and Rituxan. His research also contributed to the understanding of immune system function and the genetic diversity of antibodies. He published extensively, with key papers including:
- “Continuous cultures of fused cells secreting antibody of predefined specificity” (Nature, 1975)
- “The structure and function of immunoglobulins” (various publications in the 1970s and 1980s)

Patents and applications stemming from his work include foundational intellectual property in monoclonal antibody technology, licensed globally to pharmaceutical and biotech firms.
