Laboratory evaluation of stable isotope labeling of Culicoides (Diptera: Ceratopogonidae) for adult dispersal studies

open access: yesParasites & Vectors, 2019
Background Stable isotope labeling is a promising method for use in insect mark-capture and dispersal studies. Culicoides biting midges, which transmit several important animal pathogens, including bluetongue virus (BTV) and epizootic hemorrhagic disease

zmm28 transgenic maize increases both N uptake- and N utilization-efficiencies

open access: yesCommunications Biology, 2022
Isotope 15N labeling demonstrates that zmm28 transgenic maize have an improved N uptake during late-vegetative stages inducing N storage in lower leaves of the canopy and, thus, N uptake efficiency relative to wild-type maize.

Ultra-sensitive isotope probing to quantify activity and substrate assimilation in microbiomes

open access: yesMicrobiome, 2023
Background Stable isotope probing (SIP) approaches are a critical tool in microbiome research to determine associations between species and substrates, as well as the activity of species. The application of these approaches ranges from studying microbial

Isotope Labeling in Mammalian Cells [PDF]

open access: yes, 2011
Isotope labeling of proteins represents an important and often required tool for the application of nuclear magnetic resonance (NMR) spectroscopy to investigate the structure and dynamics of proteins. Mammalian expression systems have conventionally been considered to be too weak and inefficient for protein expression.

The Rules of Human T Cell Fate in vivo

open access: yesFrontiers 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 ...

Evolution of graphene growth on Ni and Cu by carbon isotope labeling. [PDF]

open access: yesNano letters (Print), 2009
Large-area graphene growth is required for the development and production of electronic devices. Recently, chemical vapor deposition (CVD) of hydrocarbons has shown some promise in growing large-area graphene or few-layer graphene films on metal ...
