Cysteinylglycine
Based on 1 Customer Validation
Cysteinylglycine (L-Cysteinylglycine; Cys-Gly) is a dipeptide formed by the peptide bond linkage between cysteine (Cysteine) and glycine (Glycine). Cysteinylglycine is an important metabolic intermediate in the human body, mainly derived from the degradation of glutathione (GSH). Cysteinylglycine reduces ferric iron to ferrous iron, drives the redox cycle of iron, generates reactive oxygen species (ROS), stimulates oxidative reactions, induces lipid peroxidation of human plasma LDL lipoproteins, and causes oxidative damage to DNA bases. Cysteinylglycine can be used as a biomarker to evaluate ischemic heart disease, breast cancer and other conditions.

In Vitro
Cysteinylglycine (48 h; 10 μM-50 μM) shows a significant 1.2- to 1.7-fold increase in human astrocytoma U373-MG cells after 48 h of treatment with various Nrf2 activators, compared with control cells[1].
Cysteinylglycine (0.78-25 μM; incubated at 20℃ in the dark for 10 min) can be accurately quantified by this reversed-phase ion-pair liquid chromatography method, with a linear response range of 0.78 to 25 μM, a limit of detection < 2 pmol, and the adduct can be stably stored at -80℃ for 14 days[2].
