Monoclonal antibodies (mAbs) are currently the largest and fastest-growing category of biopharmaceuticals. Since 1984, more than 60 mAbs and fusion molecules has been approvedfor use in more than 30 cancers, autoimmune and cardiovascular diseases. It is estimated that by 2024, the global market value of mAbs will reach 138.6 billion dollars.
The clinical efficacy and safety of mAbs are affected by their glycosylation structure and composition. Glycosyl distribution is usually heterogeneous, depends largely on the manufacturing process, and is therefore susceptible to changes in cell culture conditions. Therefore, it is considered a key quality attribute of mAbs. Great efforts have been made in mammalian and non-mammalian cells to control the glycosylation of mAbs. However, it is still a challenge to obtain a specific glycoform that is completely homogeneous.
The latest innovations in chemoenzymatic glycoengineering technology will allow the production of mAbs with well-defined and uniform Fc glycoforms, thereby giving them the desired biological properties. This method has significant advantages, such as enhanced Fc effector function, improved safety, higher batch-to-batch consistency, reduced immunogenicity, and can be expressed economically. Overall, producing mAbs with the innovative glycoengineering technology will bring tangible benefits to patients and manufacturers.

Mammalian host systems are the preferred expression platform because they can maximize the post-translational processing and functional activity of proteins.
Chemoenzymatic glycoengineering refers to the in vitro remodeling of glycans using enzymes such as endoglycosidase and sugar synthase.
