Non- or Simplified-Glycosylated Antibodies Service

Based on the GlycoOpitimize™ platform established through years of experiences, scientists from Creative Biolabs had successfully developed different technologies for non- or simplified-glycosylated antibodies to offer our clients with multiple options and economically feasible solutions. Our leading techniques promise our glycoengineered antibody products possessing desired structure or glycoforms without impacting the affinity and reliable for both academic and clinical applications.

Heterogeneity in the N-glycans on antibodies and other biopharmaceuticals often result in poor process reproducibility and variable therapeutic efficacy. Non-glycosylated antibodies can be generated by producing in E. coli or mutating Asn297 to either Ala or Gln. N-glycans have important structural functions. They stabilize the CH2 domain and Non-glycosylated mAbs have been shown to be less thermally stable and more susceptible to proteolysis and unfolding. However, non-glycosylated mAbs have reduced effector functions while retain the FcRn interactions and long serum half-life of wild-type IgGs, which makes them appropriate for non-cancer targets to reduce potential adverse events. Several non-glycosylated IgGs or Fc platforms have been approved (e.g. Nplate®) and some candidates are in clinical trials. Besides, our scientists can shorten the N-glycosylation pathway in the Golgi by knocking-out and knocking-in specific glycosyltransferases or glycosidases to produce simplified-glycosylated antibodies. The simplified-glycosylated antibodies share similar folding and stability profiles meanwhile possess low initial clearance from serum and reduced effector functions relative to the wild-type antibodies.

Highlighted by the GlycoOpitimize™ platform, multiple glyco-engineering techniques in Creative Biolabs are integrated as a budget and time-saving working procedure. We can not only provide production service of non- or simplified-glycosylated antibody but also cell line development, downstream biopharmaceutical processes development and analysis service. Send us your project description and needs and our talented and well-trained scientists will design a service package meeting your needs.
