The reproducibility of phospholipid analyses by MALDI-MSMS.
The identification of phosphocholine and phosphoethanolamine lipids by MALDI TOF/TOF, including characterisation of the headgroup and delineation of the acyl chain at each position of the glycerol backbone, has been explored using lipids representative of each type. The relative intensities of fragments involving the neutral loss of one or other of the acyl chains from ion adducts of 1-palmitoy...
متن کاملLactulose:Mannitol Diagnostic Test by HPLC and LC-MSMS Platforms: Considerations for Field Studies of Intestinal Barrier Function and Environmental Enteropathy
OBJECTIVES The lactulose:mannitol (L:M) diagnostic test is frequently used in field studies of environmental enteropathy (EE); however, heterogeneity in test administration and disaccharide measurement has limited the comparison of results between studies and populations. We aim to assess the agreement between L:M measurement between high-performance liquid chromatography with pulsed amperometr...
متن کاملDevelopment of a method for rapid quantitation of amino acids by liquid chromatography-tandem mass spectrometry (LC-MSMS) in plasma.
A new analytical method has been developed and is proposed for the rapid determination of eighteen common amino acids, including tryptophan, in plasma and dried blood spots, by liquid chromatography coupled with ionspray tandem mass spectrometry. Potentially the method can include other amino acids and can be used for the diagnosis of metabolic disease. The use of the ionspray tandem mass spect...

15 صفحه اولRapid Determination of Gemcitabine and Its Metabolite in Human Plasma by LC-MSMS through Micro Protein Precipitation with Minimum Matrix Effect
ISSN:0975-1459 A novel micro protein precipitation was proposed and employed effectively for bio-sample preparation of only 5 μl of human plasma for rapid liquid chromatographytandem mass spectrometric (LC-MSMS) determination of gemcitabine (dFdC) and its deaminated metabolite, 2’, 2’-difluorodeoxyuridine (dFdU).). Gemcitabine-13C, 15N2 Hydrochloride was the internal standard. Baseline chromato...
