Figure 2.

MTRasym curves of 50 mM PCr in pH 7.3 PBS at 10 different saturation powers (0.24 μT −2.35 μT) with 4 s irradiation (a) and the MTRasym at 2.6 ppm of 4 different concentrations at these powers (b). MTRasym curves of 50 mM PCr in PBS at 0.47 μT with 10 s irradiation varying pH (c) and the MTRasym at 2.6 ppm at these pH with varied saturation power with 13 s irradiation (d).
