Many biopharmaceutical developments contain oligosaccharides that affect their function, properties, and yield. CD BioGlyco utilizes specialized computer-assisted modeling services to help with quality assurance at different stages of biopharmaceutical development and manufacturing. The variability in glycosylation of biopharmaceuticals is mainly determined by the process conditions and development process. Our professional services team provides model building, model optimization, and predictive validation services. Moreover, we provide other Computational Glycoengineering-assisted Specific Modeling services such as In-silico Glycoengineering Prediction and TGP Glycosylation Prediction.
Glycosylation is a key quality attribute of biopharmaceuticals due to its close relevance to bioprocessing and its impact on pharmacokinetic safety, and pharmacodynamics. In biopharmaceutical development, glycosylation is influenced by nutrient availability, temperature, dissolved oxygen, ammonia, and pH. Glycosylation variability also exists between batches of the same drug. Relying on client-supplied data and advanced algorithms, our lab provides satisfactory predictive modeling services such as kinetic models, flux-based glycosylation models, or statistical models.
We provide not only online process inspection services but also services for predicting the impact of macro- and micro-phenomena on the yield and quality of biopharmaceuticals.
Chinese hamster ovary (CHO) and murine myeloma (NS0 and Sp2/0) cell lines are commonly used in biopharmaceutical manufacturing. Our lab provides reliable In-silico cell line glycoengineering services to clients.
Our lab uses predictive modeling combined with multivariate data analysis (MVDA) to determine the correlation between critical process parameters (CPPs) and critical quality attributes (CQAs).
Another important service related to this modeling is the analysis of chemometric relationships between nutrients, metabolites, cells, and products. Moreover, we offer kinetic analysis services for biopharmaceutical processes.
Our lab provides accurate output glycoprofile prediction services based on the known chemical, physical, and biological phenomena governing the bioprocess.

Results: In this study, researchers used an updated and optimized kinetic model to analyze N-glycosylation in several CHO cell lines. The model predicts the glycosylation process, enzyme activity profiles, and complete glycosylation profiles of each cell line in detail. The researchers adjusted the model parameters such as enzyme concentration with the help of a nonlinear fitting algorithm and MALDI-TOF-MS data. This model was developed to effectively reduce the known loss of glycosylation function in mutant cell lines.
