Identifying nonspecific ligand binding in electrospray ionization mass spectrometry using the reporter molecule method
Download2009
Sun, Nian, Klassen, John S., Kitova, Elena N., Sun, Jiangxiao
The application of the reporter molecule (Mrep) method for identifying nonspecific complexes in the ES-MS analysis of protein-ligand and DNA-ligand interactions in vitro is described. To test the reliability of the method, it was applied to the ES-MS analysis of protein-carbohydrate complexes...

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...

Klassen, John S., Yao, Yuyu, Serpe, Michael J., Xu, Wenwen
Anisotropic particles have generated an enormous amount of research interest due to their applications for drug delivery, electronic displays and as micromotors. However, up till now, there is no single protocol capable of generating particles of “patchy” composition with a variety of...

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...
