Final answer:
Monoclonal antibodies are produced by fusing antibody-producing B cells from a mouse with myeloma cells and growing them in tissue culture using hybridoma technology.
Step-by-step explanation:
Monoclonal antibodies are produced by fusing antibody-producing B cells from a mouse with myeloma cells and growing them in tissue culture. This process is known as hybridoma technology. The resulting hybridoma cells can multiply indefinitely and continue to produce antibodies specific to a single epitope.
