Mass Spectrometry - Centre for Biologics Evaluation

Health Canada, Ottawa, Ontario
What the facility does

Development and application of new mass spectrometric methods for proteomic analysis, especially of vaccines and biotherapeutic proteins including biosimilar products

Areas of expertise

The laboratory’s area of expertise is in the development and application of mass spectrometric methods to identify and characterize peptides and proteins in complex matrices especially: vaccines, stem cells, exosomes and therapeutic biologics. Employing a range of instruments, including tandem mass spectrometers, nano-ultra high pressure liquid chromatographs and cell sorters, the laboratory is also involved in the comparative proteomic analysis of complex biological materials from cells and tissues.

Research services

Comparative proteome analysis of mixtures of proteins from cell culture or tissue as well as mass spectral analysis of less complex materials such as recombinant proteins and vaccines. The bioinformatics analysis using numerous software suites is part of the analytical process.
