Descrizione generale

Sodium acetate-2-13C is 13C isotopomer labeled precursor of sodium acetate.

Applicazioni

13C labeling in the methyl group has a significant effect on the Dynamic Nuclear Polarization of acetate. Sodium acetate-2-13C labeling can be used in structural studies analyzing the interactions between lipo oligosaccharide and host proteins. Incorporation of Sodium acetate-2-13C shows enriched 13C-NMR spectra indicating their biosynthesis of microbial products and novel polyketides. Hyperpolarized 13C-acetate MRI has been applied to examinations of both rodents and porcine models.

Dynamic Nuclear Polarization

Dynamic Nuclear Polarization (DNP) is a phenomenon by which high spin polarization, typically derived from a bath of free radical electrons, is transferred to a nuclear spin bath, enhancing the difference between the nuclear energy levels and thereby producing dramatically enhanced NMR signals for detection.
