Detection Principle
亚硝酸还原酶能够将NO2-还原为NO,使样品中参与重氮化反应生成紫红色化合物的NO2-减少,重氮化反应产物在540 nm处具有特征吸收峰,通过吸光值变化即可表征亚硝酸还原酶的活性。
  • 检测方法: 萘胺比色法
  • 检测波长: 540 nm
  • 信号响应: 递减型
Refreence Information
  • 标准物质: Sodium Nitrite
  • 参考标准: y=4.7682x+0.0198 (R2=0.9992)
  • 标准线性范围: 0.0125-0.3 μmol/mL
  • 检测限: To Be Updated
  • 注:不同仪器及比色材质会对结果产生影响,以实际测定值为准。
Notices
①若测定吸光值超出标准线性吸光值范围:高于最高值建议适当增加样本量后再进行测定,低于最低值建议将粗酶液适当稀释后再进行测定;计算时相应修改;
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。
