Protea Biosciences Group Inc. that it has renewed its collaboration for further applications development of its advanced analytical software for its molecular information services with Protein Metrics Inc. By combining Protea's high-resolution mass spectrometry molecular data with the analytical power of Protein's software, Protea is delivering comprehensive molecular information to researchers who are developing complex biotherapeutics, commented David Halverson, Protea's president. This collaboration will empower researchers with bioinformatics tools to facilitate the analysis of the structure of therapeutic proteins, including their disulfide linkages, glycoforms and other structural components. As part of the extended partnership, Protea and Protein Metrics intend to create co-authored presentations this year to highlight the benefit of the combined analytical workflows with data processing and reporting capabilities.
