Monoclonal antibodies (mAbs) are one of the most fast-growing classes of the biopharmaceuticals market. The quality, safety, and potency of mAbs are determined largely by their glycosylation. Thus, detailed glycomic analyses are important to assess biotherapeutic quality and establish the equivalency of biosimilar mAbs now coming to market. However, the inherent structural diversity of glycosylation significantly hinders analysis. Here, we created glycoform database for rapid identification and structural elucidation of mAbs glycans. Glycans were released by PNGase F digestion, then enriched by porous graphitized carbon solid phase extraction. Enriched glycans were separated and analyzed by nanoLC PGCchip/Q-TOF MS and MS/MS. Accurate mass MS was used to compositionally annotate and profile the N-glycans, while CID MS/MS was used for structural elucidation. We generate DB platform which combines RT, accurate mass, diagnostic fragment ion, and identified glycan structures. Up to now, glycans from five representative mAbs including adalimumab, bevacizumab, infliximab, rituximab and trastuzumab were analyzed and total 27 glycans were incorporated to database. The glycome DB removes the bias and user-dependency associated with manual data interpretation and enables an algorithmic approach towards biopharmaceutical glycan characterization.
