Protein Characterization Services

At WuXi Biologics, our Protein Sciences (PS) Department provides comprehensive protein characterization testing to help you triage and optimize your lead candidates. Our integrated protein characterization and analytics platform includes purity/impurity testing, structure characterization assessment, including MS-based protein ID and post-translational modification analysis, and function testing, (e.g., SPR/ELISA/cell-based activity assays), among others. Notably, all these services are carried out within WuXi Biologics, eliminating the need to outsource to multiple vendors.
