Site-specific Characterization of Glycosylation on Protein Drugs

A large proportion of biotherapeutic products are glycoproteins. These include erythropoietin and various other cytokines, antibodies, glycosyltransferases, and glycosidases, which together generate sales of billions of dollars worldwide. These drugs are inherently complex, and as new treatments emerge and biosimilars are evaluated, the need to better understand the structures o
