Water dynamics in aqueous biopolymer solutions often display a two-phase character, resembling water-water and water-protein interactions. Rotationally hindered water molecules in crowded protein environments display triple exponential magnetic relaxation out of the extreme narrowing limit. Because water-protein interactions retard the water dynamics, H2O(17) magnetization passes through a NMR multiple quantum coherence filter, allowing the visualization of reorientationally hindered water without the disturbing resonance of the bulk. In vitro experiments performed on selected biological materials (lens, vitreous body and serum albumin solutions) clearly demonstrate the potential of this technique.

NMR-based metabolomics of mammalian cell and tissue cultures
Abstract NMR spectroscopy was used to evaluate growth media and the cellular metabolome in two systems of interest to biomedical research. The first of these was a Chinese hamster ovary cell line engineered to express a recombinant protein. Here, NMR spectroscopy and a quantum mechanical total line shape analysis were utilized to quantify 30 metabolites such as amino acids, Krebs cycle intermediates, activated sugars, cofactors, and others in both media and cell extracts. The impact of bioreactor scale and addition of...
