Understanding the heterogeneity of human pericyte subsets in blood-brain barrier homeostasis and neurological diseases
Preparation Condition 4 (EDTA 4 o C deproteinization): Storage at 80 o C prevents enzymatic degradation of GSH We included EDTA-treated plasma stored at 4 o C (Preparation Condition 4) as a positive control for enzymatic processes that may lead to degradation of GSH during sample storage
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
