We developed a new multiplexed reversed phase liquid chromatography-high resolution tandem mass spectrometric (LC-MS/MS) method. The method is based on isobaric labeling with a tandem mass tag (TMT10-plex) and stable isotope-labeled internal standards, and was used to analyze amino acids in mouse brain microdialysis samples.

Mosquito eggshells show remarkable diversity in physical properties and structure consistent with adaptations to the wide variety of environments exploited by these insects. We applied proteomic, transcriptomic, and hybridization in situ techniques to identify gene products and pathways that participate in the assembly of the Aedes aegypti eggshell.

Mass spectrometric analysis of microbial metabolism provides a long list of possible compounds. Restricting the identification of the possible compounds to those produced by the specific organism would benefit the identification process.

Plants contain a myriad of metabolites which exhibit diverse biological activities. However, in-depth analysis of these natural products with current analytical platforms remains an undisputed challenge due to the multidimensional chemo-diversity of these molecules, amplified by both isomerization and conjugation.

Dereplication of crude plant extracts through liquid chromatography-mass spectrometry is a powerful technique for the discovery of novel natural products. Unfortunately, this technique is often plagued by a low level of confidence in natural product identification. This is mainly due to the lack of extensive chromatographic and mass spectrometric optimizations that result in improper and incomplete MS/MS fragmentation data. This study proposes a solution to this problem by the optimization of chromatographic separation and mass spectrometry parameters.

Phytochemical analysis of the leaves of Aglaia gigantea, Aglaia dasyclada and Aglaia oligophylla collected in Vietnam yielded three terpenoids, which included two triterpene Foveolin B (1), Niloticin (2) and one tetraterpene Lutein (3). The structures of these compounds were elucidated through extensive 1D and 2D NMR spectroscopy and analysis of their mass spectrometric data.

A versatile software tool,virtualmslab, is presented that can perform advanced complex virtual proteomic experiments with mass spectrometric analyses to assist in the characterization of proteins. The virtual experimen-tal results allow rapid, flexible and convenient exploration of sample prepar-ation strategies and are used to generate MS reference databases that can be matched with the real MS data obtained from the equivalent real experi-ments.

Trypsinogen-1 and -2 are well-characterized enzymes that are expressed in the pancreas and also in several other tissues. Many cancers produce tryp-sinogen isoenzymes that differ from the pancreatic ones with respect to substrate specificity and isoelectric point.
