摘要:
We describe a method of reducing batch-to-batch variation or increasing homogeneity between batches in the production of a recombinantly expressed polypeptide. The method comprises expressing the polypeptide in a Chinese hamster ovary (CHO) cell comprising reduced UDP-galactose transporter activity compared to a wild-type CHO cell. In some embodiments, the CHO cell further comprises reduced GDP-fucose transporter activity.
摘要(中):
我们描述了减少批次间变异或增加批次间重组表达多肽产生的同质性的方法。 该方法包括在与野生型CHO细胞相比包含降低的UDP-半乳糖转运蛋白活性的中国仓鼠卵巢(CHO)细胞中表达该多肽。 在一些实施方案中,CHO细胞还包含降低的GDP-岩藻糖转运蛋白活性。
