Application of traditional and reverse labeling approaches to assess dietary bioavailability of metals in biofilms

Environment International
The accuracy of stable isotope tracing techniques, traditional and reverse labeling, in evaluating metal bioavailability remains uncertain. This study employed pulse-chase feeding combined with multi-heavy-metal stable isotope labeling to compare the ...

Reconciling Estimates of Cell Proliferation from Stable Isotope Labeling Experiments.

PLoS Computational Biology, 2015
Stable isotope labeling is the state of the art technique for in vivo quantification of lymphocyte kinetics in humans. It has been central to a number of seminal studies, particularly in the context of HIV-1 and leukemia.

18O Stable Isotope Labeling in MS-based Proteomics [PDF]

Briefings in Functional Genomics and Proteomics, 2009
A variety of stable isotope labeling techniques have been developed and used in mass spectrometry (MS)-based proteomics, primarily for relative quantitation of changes in protein abundances between two compared samples, but also for qualitative characterization of differentially labeled proteomes.

A 13C isotope labeling method for the measurement of lignin metabolic flux in Arabidopsis stems

Plant Methods, 2018
Background Metabolic fluxes represent the functional phenotypes of biochemical pathways and are essential to reveal the distribution of precursors among metabolic networks. Although analysis of metabolic fluxes, facilitated by stable isotope labeling and

The Rules of Human T Cell Fate in vivo

Frontiers in Immunology, 2020
The processes governing lymphocyte fate (division, differentiation, and death), are typically assumed to be independent of cell age. This assumption has been challenged by a series of elegant studies which clearly show that, for murine cells in vitro ...

Springtime Drought Shifts Carbon Partitioning of Recent Photosynthates in 10-Year Old Picea mariana Trees, Causing Restricted Canopy Development

Frontiers in Forests and Global Change, 2021
Springtime bud-break and shoot development induces substantial carbon (C) costs in trees. Drought stress during shoot development can impede C uptake and translocation. This is therefore a channel through which water shortage can lead to restricted shoot

Carbon stable isotope analysis of cereal remains as a way to reconstruct water availability: preliminary results [PDF]

, 2011
Reconstructing past water availability, both as rainfall and irrigation, is important to answer questions about the way society reacts to climate and its changes and the role of irrigation in the development of social complexity.

ZoomQuant: An application for the quantitation of stable isotope labeled peptides [PDF]

Journal of the American Society for Mass Spectrometry, 2005
The main goal of comparative proteomics is the quantitation of the differences in abundance of many proteins between two different biological samples in a single experiment. By differentially labeling the peptides from the two samples and combining them in a single analysis, relative ratios of protein abundance can be accurately determined.

Trajectories of plasma and CSF MTBR-tau243 and phosphorylated-tau species across the Alzheimer’s disease continuum

Nature Communications
To efficiently implement plasma and cerebrospinal fluid (CSF) biomarkers for staging and prognosis of Alzheimer disease (AD), we must understand their dynamics across disease progression.

An optimized method for measuring fatty acids and cholesterol in stable isotope-labeled cells

Journal of Lipid Research, 2017
Stable isotope labeling has become an important methodology for determining lipid metabolic parameters of normal and neoplastic cells. Conventional methods for fatty acid and cholesterol analysis have one or more issues that limit their utility for in ...
