We provide a basic determination of intact proteins under denaturing conditions, without prior digestion or gas phase fragmentation of the molecule of interest. Native protein (complex) analysis are not offered as a routine service.

We can provide information on the stoichiometry of possible chemical or post-translational modifications as well as stability of protein sample, including any degradation/proteolysis that may have occurred. In addition, through MS/MS analysis (please see PTM Analysis), the location of the modification can be determined.

Please contact us for more information concerning sample submission and sample preparation.
