At the same time,the specific reactivity and Michaelis-constant can also be determined.
利用蔗糖酶作用于蔗糖,使之转化为葡萄糖和果糖的反应,根据反应过程中旋光度的变化追踪反应进程,测定酶的比活性以及米氏常数,从而研究反应条件对酶催化作用的速率的影响。
Flies were then transferred to basic culture media to determine their fecundity and SOD activity.
2mg/mL乌鸡黑色素的培养基中培养,通过测定果蝇寿命、繁殖力和SOD比活性来分析黑色素的紫外辐射保护作用。
