Relative quantitation of glycopeptides based on stable isotope labeling using MALDI-TOF MS.
We have developed an effective, sensitive method for quantitative glycopeptide profiling using stable isotope labeling and MALDI-TOF mass spectrometry (MS). In this study, we synthesized benzoic acid-d0 N-succinimidyl ester (BzOSu) and benzoic acid-d5 N-succinimidyl ester (d-BzOSu) as light and heavy isotope reagents for stable isotope quantification for the comparative analysis of glycopeptide...
متن کامل“Quantitative Proteomics of rhGH-Doping by Multiplexed Stable Isotope Labeling and MALDI-TOF/TOF Mass Spectrometry”
The detection of doping with recombinant peptide and protein hormones (e.g. human growth hormone -hGH, erythropoietin Epo) is one of the most challenging analytical problems in doping control. Rapid metabolic degradation paired with a low medical dosing strategy reduces the time window for a successful direct detection by immunological methods in the case of hGH to just a few hours after the la...
متن کاملStable Isotope Labeling in Proteomics
Proteomics, the analysis of the proteins expressed by a cell, tissue or organism under a specific set of conditions, has undergone a tremendous period of growth in the past few years. Proteomic studies are typically designed to analyze hundreds or thousands of proteins in a single analysis and aim to provide a global view of changes in protein expression that occur in different cellular growth ...
متن کاملSensitive and rapid detection of ganciclovir resistance by PCR based MALDI-TOF analysis.
BACKGROUND Cytomegalovirus (CMV) infection is associated with significant morbidity and mortality in transplant recipients. Resistance against ganciclovir is increasingly observed. According to current guidelines, direct drug resistance testing is not always performed due to high costs and work effort, even when resistance is suspected. OBJECTIVES To develop a more sensitive, easy applicable ...
متن کاملLabeling of Human Serum Albumin with Stable Isotope of Bromine; an in Vitro Study
Background: Possibility to trace-label albumin with isotopes results in information concerning its synthesis, breakdown, and distribution in the intra and extra cellular spaces. The iodination of albumin is a widespread procedure used in scientific studies. Bromine not only is more reactive and less expensive than iodine, but bonds more easily with many elements. Therefore, it could be a suitab...
