Bioanalytical Services >> Small Molecule

Protea’s Bioanalytical Service laboratory is a state-of-the-art GLP mass spectrometry facility, featuring high resolution exact mass MS/MS technology as well as the most advanced triple quadrupole systems and software. With over 25 years of combined GLP experience in small molecule analysis, we know what it takes to deliver your compound to market, from non-GLP drug discovery through Phase 3 support in a GLP compliant laboratory. All GLP work is performed in accordance with US 21CFR Part 58, US 21 CFR Part 11, US FDA Guidance for Industry (Bioanalytical Method Validation), and current industry and regulatory practices.
