High-precision, automated peptide mapping of proteinsInstrument Type: UHPLC
The biopharmaceutical industry continues to develop protein-based biotherapeutics in increasing numbers. Due to their complexity and biotechnological production, there are many attributes that need to be analyzed to guarantee their safety and efficacy. Peptide mapping is used to measure several critical quality attributes (CQA) required for the characterization of any biotherapeutic protein. The analysis is used to confirm that the correct sequence has been expressed for the protein and to check for post-translational and chemical modifications.
Ultrafast hydrophilic interaction UHPLC analysis of 2AA labelled N-glycans from monoclonal antibodies (mAbs)Instrument Type: UHPLC
The Thermo Scientific Vanquish UHPLC system with Fluorescence detection is applied for the rapid glyco-profiling of a commercial chimeric IgG1 mAb.The separation is performed on a Thermo Scientific Accucore-150-Amide HILIC column in under 2.5 minutes. The developed methodology offers an excellent analytical platform for ultrafast glycan profile comparison of different batches of these mAbs.
Rapid sample preparation and peptide mapping analysis of top-selling monoclonal antibody therapeuticsInstrument Type: LCMSMS
The Thermo Scientific SMART Digest Kit is applied for generation of peptides from therapeutic monoclonal antibodies in 60 minutes. Peptide mapping samples were analysed on a Thermo Scientific UltiMate U3000 RSLC system coupled to a Thermo Scientific Q Exactive HF with Biopharma Option. Separation of sample peptides was performed on a Thermo Scientific Acclaim RSLC 120, C18, 2.2 µm analytical column using a 30 minute separation gradient, yielding excellent chromatographic separation and high sequence coverage.
Ultrafast hydrophilic interaction UHPLC analysis of 2-AA labelled N-glycans from monoclonal antibodies (mAbs)Instrument Type: UHPLC
The Thermo Scientific Vanquish H system with fluorescence detection is applied for the rapid glycoprofiling of a commercial chimeric IgG1 mAb. The separation is performed on a Thermo Scientific Accucore-150-Amide HILIC column in under 2.5 minutes. Developed methodology offers an excellent analytical platform for ultrafast glycan profile comparison of various production batches.
In-depth protein glycosylation comparison of an innovator monoclonal antibody by hydrophilic interaction UHPLCInstrument Type: UHPLC
The Thermo Scientific Vanquish H UHPC with Fluorescence detection is applied for the glycan profile comparison of trastuzumab innovator to a biosimilar candidate produced ‘in house’ using Chinese hamster ovary (CHO) cell line using HILIC-based chromatographic separation on Accucore 150-Amide-HILIC column. Developed methodology offers an excellent analytical platform for glycan profile comparison of multiples lots of both the innovator and biosimilar products
