Proteomic studies require analytical methods capable of separating, identifying and quantifying thousands of proteins. Consequently, developing separation methodologies with high resolving power necessary to separate complex protein samples prior to protei ...
Current proteomic strategies depend strongly on the development of analytical methodologies and instrumentation. In parallel to the development of mass spectrometry (MS) - based proteomic workflows, microfluidic devices emerged in this field as a flexible ...
With the human genome and many other eukaryotic and procaryotic genomes sequenced, the interest in life sciences is shifting towards the examination of the function, modification and regulation of the encoded proteins. Proteins are involved in virtually al ...
Two major milk whey proteins, β-lactoglobulin and α-lactalbumin, are among the main cowmilk allergens and can cause allergy even at a very low concentrations. Therefore, these proteins are interesting targets in food analysis, not only for food quality con ...
Results of the mechanistic studies of free-electron based fragmentation methods addressing peptide and protein structure analysis with mass spectrometry (MS), electron capture dissociation (ECD) and electron ionization dissociation (EID), are presented. Se ...
Electrospray ionization mass spectrometry (ESI-MS) is a powerful tool to investigate large molecules. Miniaturized microchips, as a goal of ‘Lab-on-chip’, allow various integrated analysis quickly. The coupling of functional microchips and ESI-MS is capabl ...
We present in this work experiments that push the limits of cold ion spectroscopy to the study of complex peptides and small proteins in the gas phase. Although the low temperature attainable in a cold ion trap greatly simplifies the electronic spectra of ...
A mass spectrometry-based assay combining the specificity of selected reaction monitoring and the protein ion activation capabilities of electron transfer dissociation was developed and employed for the rapid identification of hemoglobin variants from whol ...
The rules for product ion formation in electron capture dissociation (ECD) mass spectrometry of peptides and proteins remain unclear. Random backbone cleavage probability and the nonspecific nature of ECD toward amino acid sequence have been reported, cont ...
Improving qualitative and quantitative characterization of monoclonal antibodies is essential, because of their increasing popularity as therapeutic drug targets. Electron transfer dissociation (ETD)-based top-down mass spectrometry (MS) is the method of c ...
