    		Reference Standards Endogenous Metabolite Ferroptosis ROS Kinase Keap1-Nrf2 Metabolic Disease Inflammation/Immunology Cancer
    L-Cystine (Standard) is the analytical standard of L-Cystine. This product is intended for research and analytical applications. L-Cystine, the extracellular form of L-Cysteine (HY-Y0337), is a nutritionally dispensable semiessential sulfur-containing amino acid, occurring in proteins of plants and animals. L-Cystine induces Nrf2 protein elevation in a Keap1 (HY-P75897)-dependent manner and activates Nrf2 transcription factor. L-cystine can elicit cytoprotection by reducing ROS generation and protecting against oxidant- or doxorubicin-induced apoptosis. The reduced reabsorption of L-Cystine in renal tubules and its poor solubility in urine are the important causes of cystine precipitation and cystine crystal formation eventually leading to kidney stones. L-Cystine combined with L-theanine (HY-15121) enhances the production of antigen-specific IgG by increasing glutathione (GSH) levels and T helper 2 (Th2) mediated responses in mice. L-Cystine is promising for research of cystinuria and cystinosis
