Screening oligosaccharide libraries against lectins using the proxy protein electrospray ionization mass spectrometry assay
Download2016
Kitova, Elena N., Klassen, John S., Fan, Xuxin, Privé, Gilbert G., Cairo, Christopher W., Xiong, Zi Jian, Ng, Kenneth K. S., Zou, Chunxia, Eugenio, Luiz, Li, Jun
An electrospray ionization mass spectrometry (ESI-MS) assay for screening carbohydrate libraries against lectins is described. The assay is based on the proxy protein ESI-MS method, which combines direct ESI-MS protein–ligand binding measurements and competitive protein binding, to simultaneously...

Screening anti-cancer drugs against tubulin using catch-and-release electrospray ionization mass spectrometry
Download2016
Kitova, Elena N., Klassen, John S., Winter, Philip, Tuszynski, Jack A., Darestani, Reza R.
Tubulin, which is the building block of microtubules, plays an important role in cell division. This critical role makes tubulin an attractive target for the development of chemotherapeutic drugs to treat cancer. Currently, there is no general binding assay for tubulin–drug interactions. The...

Quantifying labile protein-ligand interactions using electrospray ionization mass spectrometry
Download2010
El-Hawiet, Amr, Liu, Lan, Klassen, John S., Kitova, Elena N.
A new electrospray ionization mass spectrometry (ES-MS) approach for quantifying protein—ligand complexes that are prone to in-source (gas-phase) dissociation is described. The method, referred to here as the reference ligand ES-MS method, is based on the direct ES-MS assay and competitive ligand...

Protein-glycolipid interactions studied in vitro using ESI-MS and nanodiscs: Insights into the mechanisms and energetics of binding
Download2015
Nikjah, Sanaz, Boraston, Alisdair B., Lin, Hong, Kitova, Elena N., Li, Jun, Pluvinage, Benjamin, Han, Ling Han, Klassen, John S.
Electrospray ionization-mass spectrometry (ESI-MS) analysis combined with the use of nanodiscs (NDs) to solubilize glycolipids (GLs) has recently emerged as a promising analytical method for detecting protein–GL interactions in vitro and, when applied to libraries of GLs, ranking their...

Nonspecific interactions between proteins and charged biomolecules in electrospray ionization mass spectrometry
Download2010
Soya, Naoto, Klassen, John S., Kitova, Elena N., Sun, Nian
An investigation of the nonspecific association of small charged biomolecules and proteins in electrospray ionization mass spectrometry (ES-MS) is described. Aqueous solutions containing pairs of proteins and a small acidic or basic biomolecule that does not interact specifically with either of...
