Antibody drugs, which are representative biopharmaceuticals, are glycoproteins with attached sugar chains, and it is known that the type of sugar chain affects their biological activity and function. At the Glycoengineering Institute, we prepare sugar chains with determined composition, binding positions, and binding patterns as "standard sugar chains" for use in sugar chain analysis. Recently, the company has added a lineup of standard sugar chains that are optimal for antibody analysis. These are sugar chains highlighted in the guidance for quality evaluation of antibody drugs, "3.3.1.3 Sugar Chains" (December 14, 2012, Pharmaceutical and Food Safety Bureau Notification No. 1214). Furthermore, you can select and purchase only the necessary standard sugar chains according to your needs. We also offer sugar chain analysis services utilizing these standard sugar chains, so please feel free to consult with us.
