N-Glycan Analysis of Biotherapeutics: Does N-Glycan Sample Prep Matter?

Compare and contrast the reproducibility, throughput, and ease of use of leading N-glycan sample preparation kits. Fluorescence signal and MS ionization efficiency of released and labeled N-glycans from the same amount of glycoprotein will be highlighted, to aid researchers in advancing their biotherapeutics and drug development process.

Event Overview:

Glycosylation can be a critical quality attribute (CQA) or product quality attribute (PQA) of biotherapeutic proteins, as the structure of N-linked glycans can influence protein function. Analysis of released N-glycans labeled with a dye that facilitates hydrophilic interaction liquid chromatography (HILIC) with detection by fluorescence (FLD) and/or mass spectrometry (MS) is a commonly used approach. The sample preparation step of this workflow determines data quality, consistency, and ease of use.
This webinar will:

• Present Agilent N-glycan sample preparation and HILIC/FLD/MS analysis workflows
• Discuss a side-by-side comparison of Agilent’s Gly-X InstantPC sample preparation option for this workflow with another option on the market (Waters RapiFluorMS), covering FLD and MS signal, reproducibility, and ease of use
• Show data on the preparation and analysis of released N-glycans from different biotherapeutic glycoproteins, such as rituximab (monoclonal antibody), etanercept and abatacept (Fc fusion proteins), as well as a control protein (NISTmAb).

Key Learning Objectives:

• Factors that influence selection of a sample preparation workflows for N-glycans on biotherapeutics
• HILIC LC/FLD/MS approaches for N-glycan analysis, including examples from biotherapeutics and control proteins
