A method is described which differentiates arylsulphatase A and arylsulphatase B in human urine. 4-Methylumbelliferyl sulphate serves as the substrate, and silver ions are used to inhibit arylsulphatase A activity. Using fresh urine it is possible to obtain separate values for arylsulphatase A and B when both are present, thus providing a diagnostic test for metachromatic leucodystrophy.
本文描述了一种区分人尿中芳基硫酸酯酶A和芳基硫酸酯酶B的方法。以4-甲基伞形酮基硫酸盐作为底物,用银离子抑制芳基硫酸酯酶A的活性。当两者都存在时,使用新鲜尿液可以分别获得芳基硫酸酯酶A和B的值,从而为异染性脑白质营养不良提供一种诊断测试。
