ISOTOPE-ASSISTED DIFFERENTIAL METABOLOMICS

这个子项目是众多研究子项目之一

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Obtain additional spectral information from representatives of the 100 important metabolites of Arabidopsis and populate the database. In the future, we will have a catalog containing the structures of the 10,000 or more' most-abundant small molecules in all human tissues. We will also be able to use this information to monitor their fluctuations in concentration in real time, as our bodies continually change. The purpose of this proposal is to take us one step closer to creating metabolomic technologies to fill this void. This proposal explores the use of stable isotope labeling of biological samples coupled with the analytical high sensitivity of mass spectrometry (MS) and the chemical selectivity of high-field NMR spectroscopy as enabling technologies for high-throughput analysis of metabolomes. We call this novel approach isotope assisted metabolomics.
