Practical Considerations for Improving the Productivity of Mass Spectrometry-based Proteomics

Yury Tsybin, Anton Kozhinov, Luca Fornelli, Kristina Srzentic, Unige Anna Laskay, Oxana Upir

Mass spectrometry (MS) is currently the most sensitive and selective analytical technique for routine peptide and protein structure analysis. Top-down proteomics is based on tandem mass spectrometry (MS/MS) of intact proteins, where multiply charged precur ...

Compatible Buffer for Capillary Electrophoresis and Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry

Hubert Girault, Natalia Gasilova, Liang Qiao, Hong-Xu Chen

A compatible buffer system for the coupling of capillary electrophoresis (CE) with matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) was developed. The employed interface consists of a robot to drive a sliver-covered separation capil ...

The molecular mechanisms of antimetastatic ruthenium compounds explored through DIGE proteomics

Paul Joseph Dyson, Angela Casini

DIGE (difference in gel electrophoresis) proteomics is exploited here to gain insight into the molecular mechanisms of two established ruthenium-based antimetastatic agents, namely trans-[tetrachloro (DMSO) (imidazole)ruthenate(III)] (NAMI-A) and [Ru(eta(6 ...

Iterative Method for Mass Spectra Recalibration via Empirical Estimation of the Mass Calibration Function for Fourier Transform Mass Spectrometry-Based Petroleomics

Yury Tsybin, Anton Kozhinov, Konstantin Zhurov

We describe a mass spectra recalibration method, which enables analysis of petroleum samples with Orbitrap FTMS. In this method, the mass calibration function is estimated on the basis of mass-to-charge ratios and abundances of internal calibrants without ...

Incremental Model Identification of Gas-Liquid Reaction Systems with Unsteady-State Diffusion

Benoit Till Cretegny

Identification of kinetic models and estimation of reaction and mass-transfer parameters can be performed using the extent-based identification method, whereby each chemical/physical process is treated individually. This method is used here to analyze gas- ...
