Our IgG glycan library is a mixture of nonfucosylated and fucosylated, bi-antennary glycan standards with variable sialylation released from human IgG antibody glycoprotein. They are available unlabeled and labeled with a variety of tags. We also supply an IgG glycoprotein standard for use during glycan release and labeling. “Glycosylation can significantly affect the in vivo safety and efficacy profiles of therapeutic recombinant monoclonal antibodies (rMAbs). In particular, glycans can have a marked influence on IgG Fc effector functions and changes in antibody glycosylation are a major cause of batch-to-batch variability during production. For these reasons, it is essential to measure and control antibody glycosylation accurately and reliably.” This introduction was copied from Dr. Daryl Fernandes’ article Demonstrating Comparability of Antibody Glycosylation during Biomanufacturing
