Histidine-Rich Peptide Selection and Quantification in Targeted Proteomics

Autor: Diya Ren, Fred E. Regnier, Natalia A. Penner, Benjamin E. Slentz

Publikováno v: Journal of Proteome Research. 3:37-45

Agarose based immobilized copper (II) affinity chromatography (Cu(II)-IMAC) in tandem with reversed-phase chromatography was applied to a yeast protein extract. Histidine-rich peptides were selected and, in the process, samples were substantially sim

Protein proteolysis and the multi-dimensional electrochromatographic separation of histidine-containing peptide fragments on a chip

Autor: Fred E. Regnier, Benjamin E. Slentz, Natalia A. Penner

Publikováno v: Journal of Chromatography A. 984:97-107

This paper reports a system for three-dimensional electrochromatography in a chip format. The steps involved included trypsin digestion, copper(II)-immobilized metal affinity chromatography [Cu(II)-IMAC] selection of histidine-containing peptides, an

Geometric effects of collocated monolithic support structures on separation performance in microfabricated systems

Autor: Natalia A. Penner, Fred E. Regnier, Benjamin E. Slentz

Publikováno v: Journal of Separation Science. 25:1011-1018

Twenty microfabricated COMOSS columns with varying dimensions were investigated in this work. Columns with different channel depth (1.6–10 μm) and width (2–4 μm) were studied; the size of collocated particles was also varied, including diamonds

Capillary electrochromatography of peptides on microfabricated poly(dimethylsiloxane) chips modified by cerium(IV)-catalyzed polymerization

Autor: Fred E. Regnier, Benjamin E. Slentz, Natalia A. Penner

Publikováno v: Journal of Chromatography A. 948:225-233

Vinylsulfonic acid, acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid (AMPS), 4-styrenesulfonic acid, and stearyl methacrylate were used for successful modification of the surface of poly(dimethylsiloxane) (PDMS) by cerium(IV) catalyzed polymer

Nanoliter capillary electrochromatography columns based on collocated monolithic support structures molded in poly(dimethyl siloxane)

Autor: Natalia A. Penner, Fred E. Regnier, Emilia Lugowska, Benjamin E. Slentz

Publikováno v: ELECTROPHORESIS. 22:3736-3743

Following current trends in miniaturization of analytical chemistry, an inexpensive disposable analytical tool in the form of a liquid chromatography column fabricated on a poly(dimethyl siloxane) (PDMS) chip was created. Ease of fabricating the chro
