Isomer Level Identification and Quantification of N-Linked Glycans by LC-SLIM-QTOF-MS

This project at North Carolina State University will be led by David C. Muddiman. This project is part of a larger small-group study to evaluate the variability associated with operator-associated variability in measuring released glycans from a monoclona

Industry Need

  • Enhanced and/or standardized ability to measure and quantitatively evaluate the glycan profile of a reference monoclonal antibody.

Approach

NC State University will procure an integrated LC-SLIM-QTOF-MS from Agilent Technologies. This approach will be used to measure and quantitatively evaluate the glycan profile of a reference monoclonal antibody using glycan standards as well as the glycan profile of a reference monoclonal antibody where the release was performed at a central laboratory. 

Impacts

Upon project completion, the the Agilent/MobilIon LC-SLIM-QTOF-MS and GlycoHunter will be available on a priority basis for NIIMBL-related technology and workforce activities, within any necessary constraints of the host institution, to be negotiated with NIIMBL.

Evaluate whether “community performance metrics” can be defined for NISTmAb released and/or released/labeled methods

Evaluate modes of implementation of a new quantitative glycan standard, SRM 3655

Understand if SRM 3655 can assist in harmonizing or standardizing glycan measurements

Outputs/Deliverables

  • Measured and reported peak areas for glycans detected from standard mixtures
  • Measured and reported peak areas for glycans detected from NIST mAb
  • Quantitated G0F in NIST mAb using three different forms of chemical quantitation
