Monoclonalvastaaineilla, often translated as monoclonal antibodies, are laboratory-produced molecules that act like human antibodies. In the body, antibodies are part of the immune system and help fight off infections. Monoclonal antibodies are designed to target specific parts of cells, called antigens. These antigens can be found on the surface of cancer cells, viruses, or other disease-causing agents. By binding to these specific antigens, monoclonal antibodies can trigger the immune system to attack the targeted cells, or they can directly block the function of the antigen.

The development of monoclonal antibodies involves a complex process. Typically, an animal, such as a mouse, is immunized with a specific antigen. The animal's immune system then produces antibodies against that antigen. Researchers then isolate the antibody-producing cells, fuse them with myeloma cells (cancerous plasma cells) to create hybridomas. These hybridomas can produce large quantities of a single type of antibody, hence the name "monoclonal." These antibodies are then purified and can be used for various therapeutic and diagnostic purposes.

Monoclonal antibodies have revolutionized the treatment of many diseases, including various types of cancer, autoimmune disorders like rheumatoid arthritis and Crohn's disease, and infectious diseases. They offer a more targeted approach to treatment compared to traditional therapies, potentially leading to fewer side effects. In diagnostics, monoclonal antibodies are used in tests to detect the presence of specific substances, such as in pregnancy tests or for identifying biomarkers of disease. The field continues to evolve with the development of new types of monoclonal antibodies and novel applications.
