SEC Protein aggregate analysis

Instrument Type: UHPLC

A UHPLC workflow for mAb aggregate analysis that operates continuously for weeks.

High-precision, automated peptide mapping of proteins

Instrument 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.

High resolution charge variants analysis of recombinant human IgG1K NIST mAb

Instrument Type: HPLC-CAD

The Thermo Scientific Vanquish Flex UHPLC system with UV detection is applied for the charge variants analysis of NISTmAb Humanized IgG1K monoclonal antibody using strong cation exchange-based chromatographic separation on a MAbPac SCX-10 column. The use of Thermo Scientific CX-1 pH gradient buffers enabled high resolution separation of reference material monoclonal antibody charge variants using a 30 minute gradient.

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 therapeutics

Instrument 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.
