Example Embodiment
[0048] Example 1
[0049] The settler is combined with a 1L stirring cell culture reactor for perfusion culture of hybridoma cells.
[0050] Cells: The cell line is hybridoma cell HB-58, which is deposited in ATCC (American Tissue Cell Bank), and the deposit number is Hybridoma CELL Line 187.1 (ATCC HB58). Cells are maintained in a 300ml spinner flask, and the spinner flask is placed at 37°C with 5% CO 2 In the incubator, inoculate into the reactor during the logarithmic incubation period.
[0051] The medium is Hybridoma-SFM (1X) (serum-free medium for hybridoma cell culture) manufactured by GIBCO, and the product number is 12045-035.
[0052] The included angle α between the liquid receiving port 3 and the bottom surface of the main body 1 is 45°;
[0053] When in use, the main body 1 is placed obliquely, and the angle β with the horizontal direction is 50°
[0054] Continuous perfusion culture for 60 days. Using glucose-restricted medium (glucose concentr...
