Detection Principle
琥珀酸脱氢酶能够催化琥珀酸脱氢生成延胡索酸,通过吩嗪二甲酯硫酸(PMS)递氢将2,6-二氯靛酚(DCPIP)还原,2,6-二氯靛酚在600 nm处具有特征吸收峰,通过吸光度下降速率即可表征琥珀酸脱氢酶的活性。
  • 检测方法: DCPIP法
  • 检测波长: 600 nm
  • 信号响应: 递减型
Notices

①测定过程中试剂二、试剂三和粗酶液均需置于冰上放置,以免变性或失活;

②若A1测定大于1.5或∆A大于0.3,建议将粗酶液使用蒸馏水适当稀释后再进行测定;若∆A小于0.02,建议适当延长酶促反应时间或增加上样量后再进行测定,计算时相应修改;

③准确在20 s和320 s处完成吸光值测定,以保证实验结果的准确性和重复性;若同时测定多个样本时,应使用多道移液器且分批进行测定,以确保组间反应时间一致;

④提取液A中含有约1 mg/mL的蛋白,测定粗酶液蛋白浓度时需减去提取液A自身的蛋白含量;

⑤沸水浴处理过程推荐使用螺纹盖离心管或冻存管,以确保密封效果防止水分挥发;

注: 为保证结果准确且避免试剂损失,测定前请仔细阅读说明书(以实际收到说明书为准),确认试剂储存和准备是否充分,操作步骤是否清楚,且务必取2-3个预期差异交的样本进行预测定,过程中问题请您及时与工作人员联系。
