 Thermo obtains exclusive license for the use of ETD technology  
Thermo has obtained an exclusive license for Electron Transfer Dissociation (ETD) technology from the Universoty of Virginia. ETD is an innovative new ion fragmentation technology that provides sequence information not available from conventional methods currently in use on ion trap mass spectrometers. "ETD will help shed new light on many important, unanswered questions in contemporary biology,” said Dr. Don Hunt, principal investigator at the University of Virginia. “ETD represents a landmark advance in the field of proteomics. This new methodology is a powerful and reliable analytical solution for protein characterization."

 Biomarkers Webinar  
Title: Bottom-up, label-free, high-throughput differential analysis of human plasma using an integrated fractionation/nano-ESI device coupled with LC-FTMS detection
Presenter: Jennifer Sutton, Ph.D., Thermo Electron
Abstract: Identification of protein/peptide biomarkers in plasma is a daunting analytical task due to the extremely high concentration, wide dynamic range, and sample complexity of this biological fluid. Intrinsic to traditional bottom-up strategies is the further increase in complexity of the original protein sample when it is digested into peptides. Multidimensional separations have been employed in an effort to ameliorate this problem. In this presentation, an alternative strategy for high-throughput differential analysis of human plasma is demonstrated, based on a fully automated, robust post-column split experiment in combination with gas-phase fractionation.

 Quantum Waves: Selectivity improvement for drug urinalysis using FAIMS and H-SRM  
When developing LC-MS methods, reference standards are used to establish initial conditions. Applying these initial conditions to real-world biological samples presents significant challenges including reduced signal-to-noise ratio (S/N). Biological matrices add interferences and contribute to reduced method selectivity. Bioanalytical scientists have many tools to solve selectivity problems that arise during method development.

 Proteomics: Site-specific identification of residues in peptides using MALDI  
Oxidative post-translational modifications are increasingly considered important, particularly for research associated with aging, cardiovascular disease and environmentally associated inflammation. These modifications involve reactive oxygen and nitrogen species with reactions such as nitration or nitrosylation of specific amino acids. Using proteomics tools such as mass spectrometry, it may be possible to simplify detection and screening of multiple modifications. Identification and localization of 3-nitrotyrosine residues in peptides...

 Trap Talk: Nature and extent of metabolism  
Traditionally, metabolic stability and metabolite profiling experiments are carried out as two separate assays. Metabolic stability is determined from an LC-MS analysis in SIM or SRM mode whereas metabolite identification and characterization requires an LC-MSn experiment. This paper discusses a strategy that involves the simultaneous determination of the nature and extent of metabolism by performing metabolite identification and metabolic stability measurements in a single analytical run.
