The clinical efficacy and safety of therapeutic glycoproteins are affected by the distribution, structure, and composition of their saccharide groups. The saccharide groups are usually heterogeneous due to changes in cell culture and other conditions during the manufacturing process. Therefore, the condition of glycosylation is considered a key quality attribute of therapeutic glycoproteins.
The glycoengineering expression platforms developed by CD BioGlyco are important strategies for improving the safety, consistency, and reduced immunogenicity of biological drugs. Our platforms allow the production of therapeutic glycoproteins such as mAbs with well-defined and uniform Fc glycoform. Our platforms have significant advantages, such as enhancing Fc effector functions, improving safety and batch-to-batch consistency, and reducing immunogenicity. They can also generate new antibody variants with a greatly enhaced ability to recruit immune cells.
Our team of experts has extensive expertise in the field of glycoengineering. They have assembled the most advanced technologies to provide customers with glycoengineered mammalian, Pichia pastoris, and plant cell expression systems and can also customize cell lines according to research needs. Our antibody experts can also provide you with an integrated solution for antibody glycoengineering, allowing the production of glycoproteins in both mammalian and non-mammalian cells in an economical and time-saving manner.

At present, the biopharmaceutical industry has greatly shifted its biologics production to mammalian cell expression systems. CD BioGlyco provides human, chinese hamster ovary and baby hamster kidney cell lines, etc.
The relatively simple glycosylation regulation mechanism of plant expression system is more likely to produce homogeneous glycoforms, which can also save most of the cost compared to mammalian expression systems.
CD BioGlyco has the world's leading protein and antibody glycoengineering technology platforms, and our professional scientific researchers can tailor solutions according to your needs. We hope to start the exploration of glycobiology with you.
