Abstract: The present disclosure shows, unexpectedly, that variations in cell culture performance in large-scale cell culture systems such as, for example, those used in commercial manufacturing processes, in some instances, can be attributed to often subtle variations among shear-protectant additives used during cell culture. Assessing the quality of shear-protective additives using such large-scale systems, however, is inaccurate, time-consuming and costly. To solve the problem identified, the present disclosure provides methods and compositions for evaluating the suitability of shear-protectant additives without resorting to large scale cell growth and/or protein production tests.

Abstract translation: 本公开意外地显示，在一些情况下，大规模细胞培养系统（例如在商业制造过程中使用的那些）中的细胞培养性能的变化可以归因于所使用的剪切保护剂添加剂之间经常微妙的变化 在细胞培养过程中。 然而，使用这种大规模系统评估剪切保护添加剂的质量是不准确的，耗时且昂贵的。 为了解决所确定的问题，本公开提供了用于评估剪切保护剂添加剂的适用性而不诉诸大规模细胞生长和/或蛋白质生产测试的方法和组合物。

Abstract: The present invention pertains to a cell culture medium comprising copper as a media supplement, which was shown to control recombinant protein glycosylation and methods of sing thereof. The present invention further pertains to a method of controlling or manipulating glycosylation of a recombinant protein of interest in a large scale cell culture.
