Detection Principle
NADP-苹果酸脱氢酶能够催化NADPH还原草酰乙酸生成苹果酸,NADPH在340 nm处具有特征吸收峰,通过吸光值的变化即可表征NADP-苹果酸脱氢酶的活性。
  • 检测方法: NADPH速率法
  • 检测波长: 340 nm
  • 信号响应: 递减型
Notices

①粗酶液制备过程必须在冰上进行,保持低温环境以防止酶变性失活;

②试验过程中试剂二、试剂三和粗酶液需置于冰上放置,以防止变性和失活;

③若ΔA大于0.5,建议将粗酶液适当稀释后再进行测定,计算时相应修改;

④准确在10 s和70 s处完成吸光值测定,以确保实验结果的准确性和重复性;

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。
