In the creation of a monoclonal antibody, a normal B cell (a type of lymphocyte, or white blood cell) is united with a myeloma cell (a type of cancer). This union results in the formation of cloned hybridomas (hybrid cells) that have the cancer cell’s trait of dividing endlessly and the B cell’s ability to produce a specific type of antibody. Monoclonal antibodies are designed to target specific molecules in the body. They have a variety of uses from pregnancy testing to diagnosing and treating certain diseases.
