摘要:
A system and method for controlling a mammalian cell culture process are provided. Such control of the cell culture process involves control of the level of dissolved carbon dioxide in the cell culture media and the resulting ability to prevent increases in the osmolality level is achieved by enhanced stripping of carbon dioxide with little or no damage to the mammalian cells. The disclosed methods and systems of dissolved carbon dioxide stripping include enhanced surface gas exchange mechanisms within the bioreactor vessel through the use of an upward flow impeller combined with vertical baffles to convert swirling motions of the liquid into a largely vertical flow;.
摘要(中):
提供了一种用于控制哺乳动物细胞培养方法的系统和方法。 细胞培养过程的这种控制涉及控制细胞培养基中溶解的二氧化碳的水平,并且通过增强对二氧化碳的去除而对哺乳动物细胞几乎没有或没有损伤来实现所产生的渗透压浓度增加的能力。 所公开的溶解二氧化碳汽提方法和系统包括通过使用与垂直挡板结合的向上流动叶轮将生物反应器容器内的表面气体交换机制改进,以将液体的旋转运动转化成大体垂直的流动。
