چکیده

were re-crystallized with ethanol/acetone/0.1%TFA (60:30:10, v:v). MS and MS/MS spectra were obtained fully automatically on an ultraflex MALDI–TOF/TOF mass spectrometer (Bruker Daltonics). The WARP–LCTM software controlled the intelligent precursor ion selection and BioTools 3.0 was used for ESI and MALDI spectra validation (both Bruker Daltonics). Database search: Mascot Version 2.0.05 (www. matrixscience.com) with MSDB was used. Only peptides with individual ion scores above the identity threshold (p < 0.05) were taken into account to determine identified proteins. Results were manually verified with WARP-LCTM.

ON-LINE SOLID-PHASE EXTRACTION AND LIQUID CHROMATOGRAPHY/PARTICLE BEAM-MASS SPECTROMETRY FOR DEGRADATION STUDIES OF SOME POLAR PESTICIDES IN WATER

An on-line automated method for photodegradation studies of isoproturon, diuron, atrazine, fenitrothion, and metoxuron by means of liquid chromatography/mass spectrometry (LC/MS) with particle beam (PB) interface is described. Surface water samples were first spiked with 50 µg/l of each pesticide and then exposed to the radiation of the medium-pressure mercury lamp. Next, in regular intervals o...

Matrix effect in LC-ESI-MS and LC-APCI-MS with off-line and on-line extraction procedures.

Matrix effect on mass spectrometry response was investigated with commercially available electrospray ionisation (ESI) and atmospheric pressure chemical ionisation (APCI) sources coupled with a single quadruple mass spectrometer. A post-column infusion system was used to observe the MS signal alterations of methadone, selected as the model compound, in plasma. For this purpose, two sample prepa...

Nanoflow liquid chromatography coupled to matrix-assisted laser desorption/ionization mass spectrometry: sample preparation, data analysis, and application to the analysis of complex peptide mixtures.

We report the development of a robust interface for off-line coupling of nano liquid chromatography (LC) to matrix-assisted laser desorption/ionisation-mass spectrometry (MALDI-MS) and its application to the analysis of proteolytic digests of proteins, both isolated and in mixtures. The interface makes use of prestructured MALDI sample supports to concentrate the effluent to a small sample plat...

Identification of mammalian cell lines using MALDI-TOF and LC-ESI-MS/MS mass spectrometry.

Direct mass spectrometric analysis of complex biological samples is becoming an increasingly useful technique in the field of proteomics. Matrix-assisted laser desorption/ionization mass spectroscopy (MALDI-MS) is a rapid and sensitive analytical tool well suited for obtaining molecular weights of peptides and proteins from complex samples. Here, a fast and simple approach to cellular protein p...

A comparison of nLC-ESI-MS/MS and nLC-MALDI-MS/MS for GeLC-based protein identification and iTRAQ-based shotgun quantitative proteomics.

The use of nLC-ESI-MS/MS in shotgun proteomics experiments and GeLC-MS/MS analysis is well accepted and routinely available in most proteomics laboratories. However, the same cannot be said for nLC-MALDI MS/MS, which has yet to experience such widespread acceptance, despite the fact that the MALDI technology offers several critical advantages over ESI. As an illustration, in an analysis of mode...
