产品介绍
包装量:100 mU per vial 贮存溶液 CH3COONa (pH 6.0) 20 mM Lubrol PX 0.1% BSA 0.2% 制品说明: rEGCase II 是内切性酶,作用于酸性及中性糖鞘脂,切断糖链和神经酰胺之间的连接键,生成完整的糖链和神经酰胺。本品不能切断单糖与神经酰胺之间的连接,如半乳糖或葡萄糖神经酰胺等。神经酰胺连接二糖以上的糖链时,其还原末端是半乳糖时作用弱,对红细胞糖脂作用弱,对糖基甘油脂和糖蛋白不起作用。 最适pH: pH5-6 抑制剂:1 mM的Hg2+,Zn2+,Cu2+能抑制酶活性; Ba2+,Ca2+,Mg2+,EDTA不能抑制酶活性。 使用注意: 本产品包含去污剂,不包含Activator II,因此不能作用于活细胞。 酶学委员会编号:EC 3.2.1.123 活性测定方法: 5 μl 酶溶液(使用包含 0.4% Triton X-100 的 50 mM pH5.0 CH3COONa 溶液稀释)同 10 nmol asialo GM1 在 5 μl 包含 0.4% Triton X-100 的 50 mM CH3COONa pH5.0 体系中,37℃反应 15 分钟,加入 100 μl Na2CO3-KCN 溶液(=Park- Johnson 试剂)停止反应,通过 Park and Johnson法测定释放寡糖的还原力。
