S-（5'-腺苷）-L-蛋氨酸对甲苯磺酸盐是甲基供体和酶催化甲基化的辅因子，包括邻苯二酚O-甲基转移酶（COMT）和DNA甲基转移酶（DNMT）。虽然存在于所有细胞中，但S-（5'-腺苷）-L-甲硫氨酸对甲苯磺酸盐集中在细胞肝脏中，其中发生了所有甲基化反应的85％。 S-(5′-腺苷)-L-甲硫氨酸-对甲苯磺酸盐用于治疗抑郁症、肝硬化、胆汁淤积症和退行性关节病变 用途： S-(5′-腺苷)-L-甲硫氨酸-对甲苯磺酸盐已用于细胞增殖检测。[2]它也用于甲基化检测。 S-(5'-Adenosyl)-L-methionine p-toluenesulfonate salt is a methyl donor and cofactor for enzyme-catalyzed methylations, including catechol O-methyltransferase (COMT) and DNA methyltransferases (DNMT). While present in all cells, S-(5'-Adenosyl)-L-methionine p-toluenesulfonate salt is concentrated in cells liver where 85% of all methylation reactions occur. Product description： S-(5′-Adenosyl)-L-methionine p-toluenesulfonate salt is used for the treatment of depression, liver cirrhosis, cholestasis and degenerative joint disease Application： S-(5′-Adenosyl)-L-methionine p-toluenesulfonate salt has been used for cell proliferation assay.[2] It has also been used for methylation assay
