“…Additionally, many GSSG measurements are based upon the reduction of the disulphide followed by measurement of GSH [24]. In order to avoid sample pretreatment some investigators have utilised electrochemical detection (ECD) to directly and simultaneously measure GSH and GSSG [25,26]. The sensitive nature of ECD lends itself to the analysis of GSSG which can be difficult to measure due to its low endogenous concentration.…”

“…Нами також запропонований кінетичний метод диференційного визначення АК та цистеїну (Цис) [9] у сумішах, певним недоліком якого є довготривалість та складність визначення. Досі немає простих спектрофотометричних методик визначення АК у присутності тіолів [17][18][19][20][21][22]…”

“…The nine compounds and the IS were separated within 25 min, and their LODs ranged from 0.6 to 25 ng/mL at an S/N ratio of 3. Furthermore, an ion-pairing reversed-phase-HPLC-ECD method was reported [67] in which total Cys, Hcy, and GSH were reduced by TCEP, and Met and ASA in human plasma and blood cell were determined with LODs of 60-80 pg/mL in a total analysis time of 20 min. More recently, Hannan et al reported an HPLC-ECD method for nine compounds and malondialdehyde in rabbit serum [68], allowing the endogenous antioxidant capacity and lipid peroxidation level to be monitored simultaneously.…”
