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.

Tandem UHPLC operation for high-throughput LC-MS peptide mapping analyses

Instrument Type: LCMS

To demonstrate the use of a multi-pump UHPLC system and enable tandem analysis with two columns in parallel, addressing productivity and throughput improvement of existing LC-MS methods.

In-depth protein glycosylation comparison of a biosimilar candidate by hydrophilic interaction UHPLC

Instrument Type: UHPLC

The Thermo Scientific Vanquish H system with fluorescence detection is applied for the glycan profile comparison of 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 the biosimilar product.

Label-Free Profiling of mAb O-linked Glycans by HPLC with Charged Aerosol Detection

Instrument Type: HPLC-CAD

O-glycans released by reductive ß-elimination to preserve structural integrity can be quantitatively measured by a simple direct method that minimizes sample manipulation and cleanup. Released glycans are separated with high resolution by charge, size and polarity on a mixed mode column employing both ion exchange and HILIC separation modes, using a simple, mass spectrometry compatible mobile phase.<enter final 90 characters of description>
