COMPARISON OF PEAK INTEGRATION METHODS FOR THE DETERMINATION OF ENANTIOMERIC FRACTION IN ENVIRONMENTAL SAMPLES
COMPARISON OF PEAK INTEGRATION METHODS FOR THE DETERMINATION OF ENANTIOMERIC FRACTION IN ENVIRONMENTAL SAMPLES

Brian J. Asher, Lisa A. D’Agostino, Jenilee D. Way, Charles S. Wong, and James J. Harynuk
Enantiomeric fractions (EFs) are used extensively in environmental pollutant research because of the insights on biochemical weathering available from quantifying enantiomeric composition. While this analysis is powerful, it can also be subject to significant error, depending on how...

Construction of multivalent homo- and hetero-functional ABO blood group glycoconjugates using a trifunctional linker strategy
Download2017-12-12
Daskhan, Gour, Tran, Hanh-Thuc, Meloncelli, Peter J, Lowary, Todd L, West, Lori J, Cairo, Christopher W.
The design and synthesis of multivalent ligands displaying complex oligosaccharides is necessary for the development of therapeutics, diagnostics, and research tools. Here, we report an efficient conjugation strategy to prepare complex glycoconjugates with four copies of one or two separate...

Guo, Siyuan, Zhang, Qiang M., Serpe, Michael J., Wei, Menglian, Gao, Yongfeng
A device constructed by sandwiching a thin film of poly(N-isopropylacrylamide)-co-acrylic acid (pNIPAmco-AAc) microgels between two thin layers of Au (all on a glass support) was used as a novel platform for controlled release of small molecules (drugs). In this submission, the model drug tris...

Copresentation of antigen and ligands of Siglec-G induces B cell tolerance independent of CD22
2013
Pfrengle, F., Kawasaki, N., Paulson, J. C. , Macauley, M. S.
Differentiation of self from nonself is indispensable for maintaining B cell tolerance in peripheral tissues. CD22 and Siglec-G (sialic acid-binding Ig-like lectin G) are two inhibitory coreceptors of the BCR that are implicated in maintenance of tolerance to self Ags. Enforced ligation of CD22...

De novo asymmetric synthesis of a 6-O-methyl-D-glycero-L- gluco-heptopyranose-derived thioglycoside for the preparation of Campylobacter jejuni NCTC11168 capsular polysaccharide fragments
Download2016-03-17
Todd L. Lowary, Roger A. Ashmus, George A. O'Doherty, Ying Jie Lim, Anushka B. Jayasuriya
An enantioselective de novo synthesis of a thioglycoside derivative of the 6-O-methyl-D-glycero- L-gluco-heptopyranose residue found in the Campylobacter jejuni NCTC11168 (HS:2) capsular polysaccharide is reported. The compound is obtained from a furfural-derived chiral diol in 11 steps. Notably,...

Klassen, John S., Han, Ling, Kitova, Elena N.
This study reports on the use of the catch-and-release electrospray ionization mass spectrometry (CaR-ESI-MS) assay, combined with glycomicelles, as a method for detecting specific interactions between water-soluble proteins and glycolipids (GLs) in aqueous solution. The B subunit homopentamers...

Determination of Hydrocarbon Group-Type of Diesel Fuels by Gas Chromatography with Vacuum Ultraviolet Detection
Download2016
Walsh, Phillip, Harynuk, J. James, Weber, Brandon M.
A GC-vacuum ultraviolet (UV) method to perform group-type separations of diesel range fuels was developed. The method relies on an ionic liquid column to separate diesel samples into saturates, mono-, di-, and polyaromatics by gas chromatography, with selective detection via vacuum UV absorption...

Development of an Orthogonal Protection Strategy for the Synthesis of Mycobacterial Arabinomannan Fragments
Download2015-10-28
Mycobacterium tuberculosis, the organism that causes tuberculosis (TB), has a carbohydrate-rich cell wall structure that possesses a number of immunogenic antigens. Circulating antibodies that recognize these glycans are present in patients infected by mycobacteria; detection of these antibodies...

Dissociation kinetics of the streptavidin-biotin interaction measured using direct electrospray ionization mass spectrometry analysis
Download2013
Kitova, Elena N., Klassen, John S., Deng, Lu
Dissociation rate constants (koff) for the model high affinity interaction between biotin (B) and the homotetramer of natural core streptavidin (S4) were measured at pH 7 and temperatures ranging from 15 to 45 °C using electrospray ionization mass spectrometry (ESI-MS). Two different approaches...
