    • PROBLEM TO BE SOLVED: To provide a method of producing recombinant viral vectors at high titers incorporating a variety of important advancements over the prior art.
      SOLUTION: The problem was solved by incorporating multiple features which provide enhanced production of viruses (particularly those viruses encoding exogenous transgenes). The specifically illustrated method describes a method for the high titer serum-free media production of recombinant replication defective adenoviruses containing an exogenous transgene. The invention provides methods of preparing microcarriers, methods for seeding bioreactors at high cell density, increasing the infectivity of the producer cells to the virus, methods to increase product yield through synchronization of the cell cycle of the producer cells, and methods to minimize the deleterious effects of exogenous transgenes.

    • PURPOSE: To obtain the titled antibody, by forming a hybridoma between a cell capable of producing an antibody of an animal immunized with a human interleukin and a myelomatous cell, cloning the hybriodoma, and selecting and using the specific clone.
      CONSTITUTION: A hybridoma is formed between a cell, capable of producing an antibody, and present in a spleen or cell in a lymphatic node of an animal immunized with a human interleukin 2 (IL2) and a myelomatous cell (a malignant cell from an initial tumor of a marrow), a cultivated and cloned to select clone capable of producing an antibody exhibiting the specificity for the human IL2. The resultant supernatant liquid obtained by cultivating the above-mentioned clone is purified by the purification operation, e.g. salting out or ion exchange chromatography, etc. to recover the aimed monoclonal antibody.
      EFFECT: A very small amount of the IL2 can be determined in a high sensitivity by carrying out the radioimmunoassay or enzymic immunoassay with the above- mentioned clone.
