For the quantification of sulfur metabolites in serum, the metabolites in 20 uL of serum were extracted and derivatized by NEM in 80 L of ice-cold extraction solvent (80% MeOH: 20% H2O containing 25 mM NEM and 10 mM ammonium formate, pH = 7.0) which includes stable isotope labeled internal standards (1 M [ 13 C 3 , 15 N]-cysteine-NEM, 0.1 M [ 13 C 2 , 15 N]-GSH-NEM, 2 M [D 4 ]-Cystine, 4.6 M [ 13 C 5 , 15 N 2 ]-GSSG, 5 M [D 4 ]-Hypotaurine, and 40 M [ 13 C 2 ]-Taurine followed by incubation at 4 C for 30 min
The importance of targeting glutathione levels in this condition is relevant since significant difference in glutathione and its related metabolites have been found in plasma (James et al
