This fusion creates a hybrid cell line that inherits the ability to produce a specific antibody from the B cell and the capacity for endless division from the myeloma cell, establishing a stable and renewable source of monoclonal antibodies. This medium is lethal to any unfused cells because it blocks the primary DNA synthesis pathway.
Splenocyte Fusion With Myeloma Cells: Creating Hybridoma Cells
Cell Fusion and Selection: The Creation of Hybridomas The creation of a monoclonal antibodies hybridoma begins with the meticulous immunization of a mouse or rat with the target antigen. After the animal's immune response is robust, splenocytes—white blood cells containing the antibody-producing B lymphocytes—are harvested.
The revolutionary solution, developed by Köhler and Milstein in 1975, involved immortalizing these antibody-producing cells by fusing them with myeloma cells. Highly sensitive immunoassays, including pregnancy tests, infectious disease screenings, and various forms of cancer screening, rely on the consistent and specific binding of monoclonal antibodies to detect minute quantities of biological markers with high accuracy.
Splenocyte Fusion With Myeloma Cells: Creating Hybridoma Cells
This sophisticated methodology enables the production of identical, highly specific antibodies by fusing antibody-producing B cells with immortal myeloma cells. Only the hybridoma cells, which inherit the ability to use the salvage pathway from the myeloma parent, can survive and proliferate.
