DOI: 10.1007/s13361-019-02150-5
Abstract: AbstractThere is a need in the field of biological mass spectrometry for structural tools which can report on regional, rather than solely global, structure of gaseous protein ions. Site-specific hydrogen-deuterium (H/D) exchange has shown promise… read more here.

DOI: 10.1021/acs.analchem.7b01581
Abstract: Native electron capture dissociation (NECD) is a process during which proteins undergo fragmentation similar to that from radical dissociation methods, but without the addition of exogenous electrons. However, after three initial reports of NECD from… read more here.

DOI: 10.1021/acs.analchem.8b04808
Abstract: Isomeric amino acid residues such as valine (Val) and norvaline (Nva) are common in recombinant proteins. The mis-incorporation of Nva for leucine (Leu) causes heterogeneity and in some cases even toxicity. Previous studies have shown… read more here.
