[13C;15N]-L-Tyrosine

Biosynthetic Preparation of 13C/15N-Labeled rNTPs for High-Resolution NMR Studies of RNAs

High-resolution investigations of the structure and dynamics of RNA molecules by nuclear magnetic resonance (NMR) methodologies require the production of 13 C/15 N-isotopically labeled samples. A common strategy entails the preparation of 13

Synthesis of [15N]-Labeled DNA Fragments

DNA fragments labeled with 15 N have the potential to provide novel insight into base pairing, hydration, drug/nucleic acid, and protein/ nucleic acid interactions. Synthetic routes to a variety of [15 N]-labeled pyrimidine nucleosides (1 –

34S and 15N Labelling to Model S and N Flux in Plants and Determine the Different Components of N and S Use Efficiency

In order to highlight our understanding on ecosystems functioning and resource sharing/competition, either in artificial environment or agrosystems, according to changes in the climatic conditions, it is necessary to measure accurately
