In addition, we used sensitive 14C labelling to assess turnover of three model organic nitrogen compounds — an important biogeochemical functional trait relating to nutrient availability.
Last year, rival European and U.S. teams used sensitive new measurements to discover three hot worlds roughly the size of Neptune (ScienceNOW, 31 August 2004:), which theorists regarded as plausible rocky bodies.
This review will focus on untargeted metabolomic profiling for biomarker or pathway discovery although many further studies, not referenced here, have used sensitive NMR or MS technologies for targeted metabolomics, i.e., measuring known metabolites.
We have used sensitive mass spectrometry-based analyses of fractionated eggshell matrices to validate six previously predicted eggshell proteins and to identify eleven novel components, and have characterized the expression patterns of many of their mRNAs.
