Reliable determinations of protein-ligand interactions by direct ESI-MS measurements: Are we there yet?
Download2012
Klassen, John S., Kitova, Elena N., Schnier, Paul D., El-Hawiet, Amr
The association-dissociation of noncovalent interactions between protein and ligands, such as other proteins, carbohydrates, lipids, DNA, or small molecules, are critical events in many biological processes. The discovery and characterization of these interactions is essential to a complete...

Resource allocation, water relations and crown architecture examined at the tree and stand-level in northern conifers
DownloadFall 2013
Variation in quantity of light has driven plants to employ many strategies in order to persist in high and low light. It is also a primary driver of lower branch mortality and crown recession. Fine roots and leaves are complimentary tissues representing belowground and aboveground resource...

Screening carbohydrate libraries for protein interactions using the direct ESI-MS assay: Applications to libraries of unknown concentration
Download2014
El-Hawiet, Amr, Klassen, John S., Kitova, Elena N.
A semiquantitative electrospray ionization mass spectrometry (ESI-MS) binding assay suitable for analyzing mixtures of oligosaccharides, at unknown concentrations, for interactions with target proteins is described. The assay relies on the differences in the ratio of the relative abundances of...

Separation and characterization of polycyclic aromatic hydrocarbons and azaarenes using normal phase liquid chromatography and electrospray ionization mass spectrometry
DownloadFall 2016
Normal phase liquid chromatography (NPLC) is widely used for separating petroleum into compound classes, such as polycyclic aromatic hydrocarbons (PAHs) and polar nitrogen containing compounds. The charge-transfer and hypercrosslinked polystyrene NPLC phases provide unique selectivities for PAHs....

A phenylarsenical, 3-nitro-4-hydroxyphenylarsonic acid (Roxarsone®, Rox), has been used extensively as a poultry feed additive for over 60 years. However, little is known about the concentrations of different arsenic species present in chicken meat as a consequence of feeding Rox to chickens....

Two studies examined the effects of 3 commercial cat diets varying in glycemic index (GI) based on ingredient composition and starch content (34.1, 29.5, and 23.6% NFE for high, medium, and low GI, respectively) on metabolizable energy (ME), indirect calorimetry and blood measurements. In Study...

Structure and stability of carbohydrate-lipid interactions: Methylmannose polysaccharide-fatty acid complexes
Download2016
Klassen, John S., Siuda, Iwona, Renaud, Justin, Tieleman, D. Peter, Kitova, Elena N., Liu, Lan, Mayer, Paul M., Richards, Michele R., Lowary, Todd L.
We report a detailed study of the structure and stability of carbohydrate–lipid interactions. Complexes of a methylmannose polysaccharide (MMP) derivative and fatty acids (FAs) served as model systems. The dependence of solution affinities and gas-phase dissociation activation energies (Ea) on FA...
