(a) Multi-compound polarization of four 13C biomolecules of interest: fumarate, pyruvate, urea, and bicarbonate in vitro. These data were obtained in a 10 mm NMR tube 60s following dissolution at 11.7T. Levels of polarization achieved were similar to that obtained for the individual compounds, performed using an optimized microwave frequency. T1’s in solution were similar to those obtained for the separate species. Standard deviations are reported (N=3). (b) Multi-compound polarization in vivo performed in a TRAMP mouse model at 3T.
