MALDI-TOF Baseline Drift Removal Using Stochastic Bernstein Approximation

Stochastic Bernstein (SB) approximation can tackle the problem of baseline drift correction of instrumentation data. This is demonstrated for spectral data: matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF) data. Two SB schemes for removing the baseline drift are presented: iterative and direct. Following an explanation of the origin of the MALDI-TOF basel...

New methods of microbiological identification using MALDI-TOF.

Rapid diagnosis of pathogens is decisive to guarantee adequate therapy in infections: culture methods are precise and sensitive, but rather slow. New resources are available to enable faster diagnosis, and the most promising is MALDI-TOF technology: mass spectrometry applied to microbiological diagnosis. Times as fast as 10 to 15 minutes to etiological diagnosis are possible after a positive bl...

Characterisation of phosvitin phosphopeptides using MALDI-TOF mass spectrometry.

Putative phosphopeptides produced from enzyme hydrolysis of phosvitin were identified and characterised using MALDI-TOF/MS. Phosvitin was heat-pretreated and then hydrolysed using pepsin, thermolysin, and trypsin at their optimal pH and temperature conditions with or without partial dephosphorylation. Pepsin and thermolysin were not effective in producing phosphopeptides, but trypsin hydrolysis...

MALDI Tissue Imaging of Drugs with the ultraflex MALDI TOF/TOF

MALDI-TOF MS has previously been used for imaging of large peptides and proteins embedded in tissue sections. This imaging technique is not limited to larger molecules, but can also be used to measure the presence of small molecules directly from tissue. However, for small molecule imaging the method of choice is a selected reaction monitoring approach in MS/MS mode.The benefits of parent ion i...

Characterization of Yersinia using MALDI-TOF mass spectrometry and chemometrics.

Yersinia are Gram-negative, rod-shaped facultative anaerobes, and some of them, Yersinia enterocolitica, Yersinia pseudotuberculosis, and Yersinia pestis, are pathogenic in humans. Rapid and accurate identification of Yersinia strains is essential for appropriate therapeutic management and timely intervention for infection control. In the past decade matrix-assisted laser desorption ionization ...
