Liu, Yiquan (2015-10-28)Activity based protein profiling (ABPP) is a functional proteomic technology that uses chemical probes to detect mechanistically related classes of enzymes. Chemically probing a certain class of proteins helps to understand ...
-
Ruotolo, Brandon Thomas (Texas A&M University, 2005-08-29)Separations coupled to mass spectrometry (MS) are widely used for large-scale protein identification in order to reduce the adverse effects of analyte ion suppression, increase the dynamic range, and as a deconvolution ...
-
Morgan, Joseph William (Texas A&M University, 2006-04-12)The design and incorporation of a decelerating/accelerating cell into a reflectron time-of-flight mass spectrometer is described for the examination of promptly-formed photodissociation products of peptide ions. The ...
-
Espinosa Garcia, Irma Leticia (Texas A&M University, 2006-10-30)Lipoprotein(a) (Lp(a)) has been described as an emerging risk factor for cardiovascular disease. The complexity of the Lp(a) molecule sets a challenge for the determination of the risk it represents for the cardiovascular ...
-
Mangold, Raymond A. (Texas A&M University. Libraries, 1986)Analytical atomic emission spectroscopy has been advanced greatly by the introduction of the plasma as an emission source. The high excitation which it obtains make it an excellent choice for atomic analysis. Still today ...
-
Van Dyke, Leon Scott (Texas A&M University. Libraries, 1993)Composites of electronically conductive polymers with insulating host materials are investigated. In this context, the author has attempted to accomplish the following objectives: i) A template synthesis method was developed ...
-
Ogugbuaja, Victor Oby (Texas A&M University. Libraries, 1984)Element bioaccumulation from 2.3 (mu)m hopper ash obtained from a power plant burning Southeast Ohio coal has been investigated. Experiments were designed to examine relationships among exposure route, dose mass, and ...
-
Aardema, Megan Nicole (2023-07-11)Understanding ozone photodissociation dynamics is a key component to accurately modeling atmospheric chemistry, and the energy partitioning into the fragments and its wave-length dependence can be used to assess the potential ...
-
Zhao, Zhi (2013-06-21)Patterned arrays of metallic nanostructures are commonly used in photonics, electronics, as well as functional materials and biotechnology because of their unique electronic and optical properties. Although great effort ...
-
Factors Affecting the Fragmentation of Peptide Ions: Metal Cationization and Fragmentation Timescale Kmiec, Kevin (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, ...
-
Trefethen, Jared M. (Texas A&M University, 2005-02-17)The primary objective was to study the kinetics of folding of RNase Sa. Wild-type RNase Sa does not contain tryptophan. A tryptophan was substituted at residue 81 (WT*) to allow fluorescence spectroscopy to be used to ...
-
Chen, Liuxi (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 ...
-
Mclean, John A.; Russell, David H.; Schultz, Albert J. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2006-07-25)A method and device for the gas-phase separation of ionic biomolecules including peptide, and protein or inorganic cluster ions or nanoparticles by ion mobility and for depositing them intact on a surface in a spatially ...
-
Blase, Ryan Christopher (2012-02-14)Drift tube ion mobility spectrometry (IMS) is a powerful, post-ionization separation that yields structural information of ions through an ion-neutral collision cross section. The ion-neutral collision cross section is ...
-
Salinas, Silvia Adriana (Texas A&M University, 2004-09-30)Gas phase chemiluminescence nitrogen specific detector (CLND)is used for the direct analysis of underivatized nitrogen-containing components such as alkylamines that can not be detected by the so called universal HPLC ...
-
Zinnel, Nathanael (2014-04-25)Mass spectrometry (MS) has been established as important analytical tool in the characterization of an array of analyte classes, including biological samples. However, without hyphenation with other techniques, the approach ...
