Detection Principle
莽草酸脱氢酶能够催化莽草酸和NADP产生NADPH,NADPH在340 nm处具有特征吸收峰,通过测定吸光值的增加速率即可表征莽草酸脱氢酶活性。
  • 检测方法: NADPH速率法
  • 检测波长: 340 nm
  • 信号响应: 递增型
Notices

①提取后上清液应置于冰上待测,且样本提取完成后建议2 h内测定以免失活;

②提取液中含有一定浓度蛋白(约1 mg/mL),样品测定蛋白浓度时需扣除提取液自身蛋白浓度;

③若∆A大于1,建议将样品稀释后再进行测定,若∆A小于0.01,可以延长反应时间(10 min或 15 min)进行测定,计算时相应修改;

④空白组为检测各试剂组分质量的检测孔,正常情况变化不超过0.01;

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。
