Margaret Doherty, PhD - Technology Development

Current Area of Interest


My role within NIBRT is to further advance our current high-throughput technology and develop a fully automated system utilizing a robotic platform.

Current analytical approaches to obtaining detailed product quality data require extensive sample preparation (e.g. to release and label glycans) and analysis (e.g., HPLC or CE-LIF, LC-MS peptide mapping), which delay the generation of key information. The ability to obtain rapid information, particularly regarding glycoform structures on-line would greatly enhance process development and optimization. Ultimately the robotic platform will be interfaced directly with processing operations to enable monitoring of cell culture conditions and the acquisition of real-time information to ensure optimized product quality.

Other aspects of my post include development and optimization of methodologies for O-glycan release and analysis, N-glycan analysis, beta testing of innovative products to facilitate glycan analysis, development of proprietary databases for IgG analysis and technology transfer.
