摘  要:
采用40—60目氧化硅胶作吸附剂,通过色谱层析和硫酸铵盐析分离提取了尿激酶(UK),并对粗品中酶的活力进行了测定,为45IU/ml,同时对蛋白质组分进行了SDS—聚丙烯酰胺凝胶电泳(PAGE)分析。电泳结果显示11条区带,其中1~2条着色较深的区带与标准尿激酶(比活13万/mg蛋白)的区带的迁移率基本相同。表明选用40—60目硅胶粗提尿激酶具有较好的吸附和分离效果。

摘  要:
A simple methed of crude extract of urokinase (UK) was set up, Crude extract of UK were isolated from and abstracted by abstroption Chromatography (on oxidation sillicugel) and andammonium dulfate salting out from human urine and meawred urominase activity, Its value was 45 IU/mg, the components in the crude extracts could also be traced and analysed by SDS-Polyacrylamide gel elec-trophoresis, The result showed eleven bands in SDS electrophoresis, one to two were as the same as the mobility of the partly purified Urokinase (the specific activity of 13×10~4IU/mg protien). All of these show that our method can be applied in practice for separate Urokinase from urine.
