Metabolic Labeling of Microorganisms with Stable Heavy Nitrogen Isotopes (15N)
2018Quantitative Proteomics based on stable isotope labeling by 15N is a versatile method in determination of changes in microbial protein expression profiles. Once set up, the workflow relies on defined chemical or commercially available complex media leading to universal heavy labeling by the stable isotope 15N.

Carbon, Nitrogen and Oxygen Stable Isotope Ratios in Chitin
2010Stable isotope ratios in chitin are firmly imprinted during biopolymer biosynthesis and reflect dietary, metabolic, and environmental influences. Chitin is a chemically complex amino sugar biopolymer that also includes non-amino-sugar moieties with contrasting isotopic compositions.

Stable nitrogen isotopic composition of wine: a preliminary investigation
2013The 15N/14N ratio has been measured in several foods to trace geographical origin and agricultural systems, but not yet in wine. In this work we developed a method for measuring 15N/14N in bulk wine, following dealcoholisation and dehydration. The δ15N of wine did not change after freeze-drying the sample or evaporating it under vacuum, obtaining ...
