A derivatization and validation strategy for determining the spatial localization of endogenous amine metabolites in tissues using MALDI imaging mass spectrometry.
J. Mass Spectrom. 49(8) , 665-73, (2014) Imaging mass spectrometry (IMS) studies increasingly focus on endogenous small molecular weight metabolites and consequently bring special analytical challenges. Since analytical tissue blanks do not exist for endogenous metabolites, careful consideration mus... |

Lysine-directed staining of proteins for MS-based analyses.
Electrophoresis 34(3) , 401-4, (2013) Visualization of proteins and MS-based analyses are elemental tasks in modern biochemistry. Nevertheless, reports about covalent protein dyes and their suitability for subsequent MS experiments remain scarce. In a recent work, we demonstrated that covalent pr... |

Fast liquid chromatography/tandem mass spectrometry determination of cannabinoids in micro volume blood samples after dabsyl derivatization.
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 905 , 85-95, (2012) Due to the non-polar nature and the absence of an ionizable group on the cannabinoids, the ionization efficiency in electrospray is low and leads to poor limits of detection (LOD). The reaction of chloride dabsyl with the phenolic OH group of cannabinoids res... |
