This work describes results of an interlaboratory study on the glycosylation of the Primary Sample (PS) of NISTmAb, a monoclonal antibody reference material. Seventy-six laboratories from industry, university, research, government, and hospital sectors in Europe, North America, Asia, and Australia submitted a total of 103 reports on glycan distributions. The principal objective of this study was to report and compare results for the full range of analytical methods presently used in the glycosylation analysis of mAbs. Therefore, participation was unrestricted, with laboratories choosing their own measurement techniques. Protein glycosylation was determined in various ways, including at the level of intact mAb, protein fragments, glycopeptides, or released glycans, using a wide variety of methods for derivatization, separation, identification, and quantification. Consequently, the diversity of results was enormous, with the number of glycan compositions identified by each laboratory ranging from 4 to 48. In total, one hundred sixteen glycan compositions were reported, of which 57 compositions could be assigned consensus abundance values. These consensus medians provide community-derived values for NISTmAb PS. Agreement with the consensus medians did not depend on the specific method or laboratory type. The study provides a view of the current state-of-the-art for biologic glycosylation measurement and suggests a clear need for harmonization of glycosylation analysis methods.}, number={1}, journal={Molecular & Cellular Proteomics}, publisher={American Society for Biochemistry & Molecular Biology (ASBMB)}, author={De Leoz, Maria Lorna A. and Duewer, David L. and Fung, Adam and Liu, Lily and Yau, Hoi Kei and Potter, Oscar and Staples, Gregory O. and Furuki, Kenichiro and Frenkel, Ruth and Hu, Yunli and et al.}, year={2019}, month={Oct}, pages={11–30} } @article{kottke_lee_jonke_seneviratne_hecht_muddiman_torres_fedorov_2017, title={DRILL: An electrospray ionization-mass spectrometry interface for improved sensitivity via inertial droplet sorting and electrohydrodynamic focusing in a swirling flow}, volume={89}, DOI={10.1021/acs.analchem.7b01555}, number={17}, journal={Analytical Chemistry}, author={Kottke, P.
