L-Methionine sulfoximine (MSX)

Dangerous Goods

CAS number:15985-39-4    molecular formula:C5H12N2O3S

overview

compound introduction

L-Methionine [R,S]-Sulfoximine inhibits both γGCS g-glutamylcysteine synthetase and Gl Syn (glutamine synthetase). Working concentrations for inhibition of g-glutamylcysteine synthetase are 0.2-2.0 mM (52% inhibition occured at 100 mM).L-甲硫氨酸亚砜亚胺已被用作谷氨酰胺合成酶(GS)活性的一种有效抑制剂。 作为谷氨酰胺合成酶活性的一种有效抑制剂,该试剂可广泛用作中国仓鼠卵巢(CHO)和其他哺乳动物细胞系中质粒整合的一种选择剂。 对用于生产治疗性重组蛋白的高产细胞库不断增长的需求导致了两种用于选择稳定和活性克隆的主要系统,二氢叶酸还原酶(DHFR)过表达细胞的甲氨蝶呤选择和谷氨酰胺合成酶过表达细胞的MSX选择。 细胞在缺乏谷氨酰胺的培养基中生长,而对谷氨酰胺合成酶内源活性的抑制则导致了缺乏过表达的细胞死亡。这种MSX-谷氨酰胺合酶选择机制相对于甲氨蝶呤-DHFR系统具有更多优势,因其通常只需要单个扩增步骤便能实现产生高稳定性、高度扩增克隆时间的显著减少。 L-Methionine [R,S]-Sulfoximine inhibits both γGCS g-glutamylcysteine synthetase and Gl Syn (glutamine synthetase).
