Protein quality is a topic of increasing importance as quality elements can have a significant impact on clinical behavior of a molecule. This talk will explore approaches to modify glycan patterns contribute to predicting, achieving and maintaining preferred glycosylation profiles.
Glycosylation is a key product quality attribute for many biotherapeutic proteins expressed in CHO cells. N-linked glycans may display macro- and micro-heterogeneity; the degree of this variation can depend on several factors, including cell line, media/feeds, and process. As a consequence, it has often been challenging to predict, achieve and maintain preferred glycosylation profiles from cell culture development through bioreactor scale-up.
