Structural mass spectrometry (MS3D) offers various methodologies for characterization of protein structure. At BIOCEV we offer different labelling approaches including hydrogen/deuterium exchange, covalent labelling, chemical cross-linking and limited proteolysis. We are equipped with cutting-edge technologies including high-resolution mass spectrometer, HPLC system, H/D system and in-house software for data processing. The service we provide includes data processing and reporting ready for publication. Besides the MS3D we offer the following services: Identification and quantification of proteins. Precise determination of protein molecular mass. Characterization of various posttranslational modifications.
