产品使用指南

摩尔计算器

L-Cystine (Standard) 是 L-Cystine 的分析标准品。本产品用于研究及分析应用。L-Cystine，L-Cysteine (HY-Y0337) 的细胞外形式，是一种营养上不可缺少的半必需含硫氨基酸，存在于动植物蛋白质中。L-Cystine 以依赖 Keap1 (HY-P75897) 的方式诱导 Nrf2 蛋白升高，激活 Nrf2 转录因子。L-Cystine 可以通过减少 ROS 的产生和保护细胞免受氧化或阿霉素诱导的细胞凋亡。L-Cystine 在肾小管中的重吸收减少和在尿液中的差溶解度是导致胱氨酸沉淀和胱氨酸晶体形成的重要原因，最终导致肾结石。L-Cystine 与 L-theanine (HY-15121) 通过提高小鼠谷胱甘肽 (GSH) 水平和 T helper 2 (Th2) 介导的应答来增强抗原特异性 IgG 的产生。L-Cystine 有望用于胱氨酸尿症和胱氨酸病的研究

生物活性

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

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
