Purpose To prepare high activity and high yield thrombin from bovine blood.

目的从牛血浆中制备高活力及高收率的凝血酶。

youdao

Activity recycle ratio of immobilized thrombin prepared by physical adsorption method is 81%, higher than that by chemical covalent binding method (56%).

实验结果表明，物理吸附法固定化凝血酶的活性回收率(81%)高于化学结合法固定化凝血酶的最佳结果(56%)。

youdao

Based on the arginine esterase activity, the thrombin-like enzyme accounted for about 60% of the total.

其中类凝血酶的精氨酸酯酶活力最高，约占总酯酶活力的60%。
