(2020-07-22)The Arctic Ocean is characterized by broad continental shelves, large river inputs, sea ice coverage, and limited exchange with other major ocean basins. This provides a unique environment in which to examine the distribution ...
-
(2022-12-08)The ever-changing global geopolitical landscape greatly influences how nuclear threats grow and evolve. To counteract these threats, equal growth must be present in the research and development (R&D) sector to counter the ...

The development of protein tags that enable the analysis of proteins with high multiplexity, in the context of cellular interactions. Nanoparticle and metal chelated tags were developed and utilized by Secondary Ion Mass ...
-
(Texas A&M University, 2004-09-30)The gas-phase hydrogen/deuterium (H/D) exchange of protonated di- and tripeptides containing a basic amino acid residue has been studied with a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer. Bimolecular ...
-
(2013-11-22)Recent progress has been made developing ion mobility-mass spectrometry (IM-MS) instruments for biophysical studies; however, experimental techniques that can probe the structure and/or dynamics of biomolecules at intermediate ...

Factors Affecting the Fragmentation of Peptide Ions: Metal Cationization and Fragmentation Timescale (2012-10-19)The factors affecting peptide fragmentation have been extensively studied in the literature in order to better predict the fragment ion spectra of peptides and proteins. While there are countless influences to consider, ...
-
(2022-12-08)In recent years, native mass spectrometry (nMS) has continued to grow in popularity and recognition as an excellent structural biology tool. The implementation of orthogonal methods to nMS, such as liquid chromatography ...
-
(2012-10-19)Ion mobility spectrometry (IMS) separates ions on the basis of ion-neutral collision cross-sections (CCS, [omega]), which are determined by the geometry or conformation of the ions. The size-based IM separation can be ...
-
(2012-08-17)We hypothesized that carcass subcutaneous fat location would affect sensory and quality traits. Five carcass fat sources were tested: brisket, chuck, plate, flank, and round. Ground beef was formulated using each fat source ...
-
(2016-07-28)Electrospray ionization (ESI) combined with ion mobility-mass spectrometry (IMMS) provides a means to directly measure the three-dimensional shape(s) of intact biomolecular ions allowing for the structural investigation ...
-
(2011-08-08)Copper ions (Cu⁺, Cu²⁺) play important roles in many biological processes (i.e., oxidation, dioxygen transport, and electron transfer); many of the functions in these processes result from copper ions interacting with ...
-
(Texas A&M University, 2006-04-12)Ion mobility-mass spectrometry (IM-MS), gas-phase hydrogen/deuterium (H/D) exchange ion molecule reactions and molecular modeling provide complimentary information and are used here for the characterization of peptide ion ...
-
(2012-07-16)The overall goal of this research was to investigate oxidative stress related changes to the proteomes of 3T3-L1 adipocytes and an inducible CYP2E1 expressing HepG2 cells. Enhanced oxidative stress in hypertrophic adipocytes ...

Statistical Assessment of Time and Mass Alignment Quality in Liquid Chromatography-Mass Spectrometry (2011-01-11)This research evaluated the efficacy of an alignment quality algorithm and follows its development. Proteomics research frequently involves liquid chromatography-mass spectrometry (LC-MS) methods for data collection. To ...
-
(2016-11-01)Phosphonates are a class of organophosphorus compounds with a characteristic carbon–phosphorus bond. The carbon–phosphorus lyase complex, encoded by the genes phnGHIJKLM, catalyzes the cleavage of the stable carbon–phosphorus ...
-
(2009-05-15)Peptide synthesis and metal doping, combined with mass spectrometric and ion mobility spectrometric techniques, have provided a picture of the fragmentation behavior of a large field of homologous peptide ions, represented ...
