L-(+)-麦角硫因适用于研究它与2,2′- 和4,4′-联吡啶二硫化物（2-Py-S-S-2-Py和4-Py-S-S-4-Py）的反应性。 它也可用于实验细胞的孵育，同时进行ATM（Ataxia毛细血管扩张症突变）或ATR （ATM-和RAD3-相关）的体外激酶活性测定。 L-(+)-麦角硫因已被用于： 1、作为卵丘-卵母细胞复合物(COC)成熟培养基的组成部分，检测其对脂质过氧化形成的保护作用； 2、作为一种抗氧化化合物用于检测2型糖尿病患者； 3、作为可溶性载体蛋白22A4 (SLC22A4)转运检测的阳性对照。 Ergothioneine is a stable antioxidant that can be found under conditions of excessive oxidative stress in plant and animal tissue. Ergothioneine can scavenge free radicals and protect cells from UV-induced ROS with higher efficiency than antioxidants coenzyme Q(10) or idebenone. The compound could be a non-toxic thiol buffering antioxidant, enhance cell viability induced by hydrogen peroxide (H2O2), and inhibit DNA oxidation by peroxynitrite (ONOO-) in the human neuronal hybridoma cell line (N-18-RE-105). An antioxidant and free radical scavenger Application： L - (+) - ergot sulfur is suitable for studying its reactivity with 2,2 '- and 4,4' - bipyridine disulfides (2-Py-S-S-2-Py and 4-Py-S-S-4-Py). It can also be used for the incubation of experimental cells and for in vitro kinase activity measurement of ATM (Ataxia telangiectasia mutation) or ATR (ATM - and RAD3- related). L - (+) - ergot has been used to: 1. As a component of the cumulus oocyte complex (COC) maturation medium, its protective effect on lipid peroxidation formation was tested; 2. As an antioxidant compound, it is used to detect type 2 diabetes patients; 3. As a positive control for soluble carrier protein 22A4 (SLC22A4) transport detection.
