Advanced proteomic liquid chromatography

Advanced high-performance liquid chromatography method development. Discovering unexpected choices in chromatography.

The influence of some important experimental parameters on the resolution of compounds as well as the validity of widely used rules of thumb and of common expectations about how to improve resolution is discussed. It will be shown, on the basis of selected examples, that the general expectations about how the experimental parameters have to be adjusted for better resolution does not cover all c...

Ion Exclusion Chromatography: Liquid Chromatography

terials, operated in a pressure-driven mode, plotted as a function of inverse temperature. This Rgure is intended to give some appreciation of the Suxes that are attainable; however, they are not normalized to a given partial pressure gradient or thickness of membrane, and thus the Suxes are not directly comparable. Taking a value of between 10 and 100 L m 2 min 1 as the level of oxygen Sux nee...

Informatics Platform for Global Proteomic Profiling and Biomarker Discovery Using Liquid Chromatography-Tandem Mass Spectrometry*□S

We have developed an integrated suite of algorithms, statistical methods, and computer applications to support large-scale LC-MS-based gel-free shotgun profiling of complex protein mixtures using basic experimental procedures. The programs automatically detect and quantify large numbers of peptide peaks in feature-rich ion mass chromatograms, compensate for spurious fluctuations in peptide sign...
