Klassen, John S., Yao, Yuyu, Kitova, Elena N., Richards, Michele R.
The results of an investigation into the influence of sulfolane, a commonly used supercharging agent, on electrospray ionization mass spectrometry (ESI-MS) measurements of protein–ligand affinities are described. Binding measurements carried out on four protein–carbohydrate complexes, lysozyme...

Serpe, Michael J., Zhang, Qiang M., Li, Xue, Islam, Molla R., Wei, Menglian
4,40 -Di(acrylamido)-azobenzene was used as a crosslinker in poly(Nisopropylacrylamide)-based microgels. The microgels were subsequently used to fabricate microgel-based optical materials (etalons), which exhibited optical properties that were switchable upon exposure to UV irradiation. We also...

Berg, Darren, Mugo, Samuel M., Zhang, Qiang M., Serpe, Michael J.
Lipase-modified pH-responsive poly(N-isopropylacrylamide)-based microgels were synthesized. An optical device was subsequently fabricated by sandwiching the enzyme loaded responsive microgels between two thin Au layers, and their response to triolein, a model triglyceride, was investigated. The...

Localizing carbohydrate binding sites in proteins using hydrogen/deuterium exchange mass spectrometry
Download2016
Kitova, Elena N., Klassen, John S., Eugenio, Luiz, Li, Jun, Ng, Kenneth, Zhang, Jingjing
The application of hydrogen/deuterium exchange mass spectrometry (HDX-MS) to localize ligand binding sites in carbohydrate-binding proteins is described. Proteins from three bacterial toxins, the B subunit homopentamers of Cholera toxin and Shiga toxin type 1 and a fragment of Clostridium...

Mapping protein-ligand interactions in the gas phase using a functional group replacement strategy: Comparison of CID and BIRD activation methods
Download2013
Klassen, John S., Deng, Lu, Kitova, Elena N.
Intermolecular interactions in the gaseous ions of two protein–ligand complexes, a single chain antibody (scFv) and its trisaccharide ligand (α-D-Galp-(1→2)-[α-D-Abep-(1→3)]-α-Manp-OCH3, L1) and streptavidin homotetramer (S4) and biotin (B), were investigated using a collision-induced...

Measuring positive cooperativity using the direct ESI-MS assay: Cholera toxin B subunit homopentamer binding to GM1 pentasaccharide
Download2014
Lin, Hong, Klassen, John S., Kitova, Elena N.
Direct electrospray ionization mass spectrometry (ESI-MS) assay was used to investigate the stepwise binding of the GM1 pentasaccharide β-D-Galp-(1→3)-β-D-GalpNAc-(1→4)[α-D-Neu5Ac-(2→3)]-β-D-Galp-(1→4)-β-D-Glcp (GM1os) to the cholera toxin B subunit homopentamer (CTB5) and to establish...
