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...

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...

Spring 2014
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...

Chemical, Enzymatic and Chemo-enzymatic Synthesis of Complex Oligosaccharides as Probes of Glycan Functions
DownloadSpring 2016
Carbohydrates, an essential class of biomolecules, mediate a variety of biological processes. Recent advances in chemical, enzymatic and chemo-enzymatic synthesis have facilitated access to an increasing number of structurally well-defined oligosaccharides. These molecules are serving as...

The Design, Synthesis and Evaluation of Multivalent Heterobifunctional Ligands Specific for Shiga Toxin 1 and Shiga Toxin 2
DownloadSpring 2014
Hemolytic uremic syndrome (HUS) is a potential life-threatening condition caused by infection with Shiga toxin-producing Escherichia coli O157:H7. There are two major types of Shiga toxins, namely, Shiga toxin 1 (Stx1) and Shiga toxin 2 (Stx2), of which, Stx2 is clinically most closely associated...

Carbohydrate-lipid interactions: Affinities of methylmannose polysaccharides for lipids in aqueous solution
Download2012
Sun, Nian, Klassen, John S., Bai, Yu, Liu, Lan, Xia, Li, Lowary, Todd L.
The interactions between 3-O-methyl-mannose polysaccharides (MMPs), extracted from Mycobacterium smegmatis (consisting of a mixture of MMP-10, -11, -12 and -13) or obtained by chemical synthesis (MMP-5s, -8s, -11s and -14s), and linear saturated and unsaturated fatty acids (FAs), and a commercial...

Quantifying protein-carbohydrate interactions using liquid sample desorption electrospray ionization mass spectrometry
Download2015
N. Kitova, Elena N., Shams-Ud-Doha, Km, Yao, Yuyu, Klassen, John S., Daneshfar, Rambod
The application of liquid sample desorption electrospray ionization mass spectrometry (liquid sample DESI-MS) for quantifying protein–carbohydrate interactions in vitro is described. Association constants for the interactions between lysozyme and β-D-GlcNAc-(1 → 4)-β-D-GlcNAc-(1 → 4)-D-GlcNAc and...

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...
