Role of Upstream Processing in Biologic Quality
The quality of biologic products is strongly influenced by upstream processing conditions. Factors such as cell health, culture environment, and nutrient availability affect product structure and functionality.
Post-translational modifications, including glycosylation, occur during upstream processing. Variations in culture conditions can alter these modifications, impacting product efficacy.
Consistent control of parameters ensures uniform product attributes. Any deviation may lead to variability that complicates downstream purification.
Upstream decisions shape final product quality, making this phase critical for achieving desired biological activity.
