Sampleprep Summary: | Urine aliquots were thawed and prepared by adding 75 μL of a chemical shift standard (Chenomx Inc., Edmonton, Alberta, Canada) containing 4.6 mM 2,2-dimethyl-2-silapentane-5-sulfonate-d6 sodium salt (DSS-D6), 0.20% w/v NaN3 and 98.0% v/v D2O, to 675 μL of urine. Samples were titrated to a final pH of 6.75 ± 0.05 using small volumes of sodium hydroxide (NaOH) and hydrochloric acid (HCl). Samples were centrifuged for 10 minutes at 10000 x g at 4 °C to remove particulate matter. Next, 700 μL of supernatant was transferred to a 4” long, 5 mm diameter NMR tube (Wilmad, Nuena, NJ, USA 505-PS-4) immediately prior to NMR acquisition. |
