For biotherapeutic proteins to be effective, they must be produced in biologically active forms with proper folding and post-translation modifications (PTMs). Thermo Scientific™ PepFinder™ software provides accurate identification, in-depth characterization, and relative quantitation of biotherapeutic and other proteins from mass spectrometric data. It provides automated workflows for glycopeptide identification, disulfide bond mapping, and quantification of PTMs. PepFinder software automates previously time-consuming manual processes, processing complex data and integrating the results into concise, informative reports.
