Hybridoma technology is a new biotechnological approach for commercial production of

1. The question asks about the application of Hybridoma technology in commercial production. 2. Hybridoma technology involves fusing an antibody-producing B-cell with an immortal myeloma cell. 3. The resulting hybridoma cell line can be cultured indefinitely and produces large quantities of a single, specific type of antibody. 4. These highly specific antibodies are known as monoclonal antibodies (mAbs). 5. Therefore, Hybridoma technology is a key biotechnological approach for the commercial production of monoclonal antibodies (A), used in diagnostics and therapeutics. Other options like interferon (B), general polyclonal antibodies (C), or alcohol (D) are produced differently.
