Detection Principle
D-乳酸脱氢酶(D-LDH)能够催化D-乳酸生成丙酮酸,同时使NAD+还原生成NADH和H+,在1-mPMS作用下,WST-1能够与NADH反应生成水溶性甲瓒,产物在450 nm处具有特征吸收峰,通过吸光值变化即可定量检测D-乳酸的含量。
  • 检测方法: WST-1法
  • 检测波长: 450 nm
  • 信号响应: 递增型
Notices

①提取液A中含有蛋白沉淀组分,待测样本不能用于蛋白含量测定;若使用蛋白浓度计算D-乳酸含量,则需要另取样本使用PBS或生理盐水按照相同步骤制备为待测样本,再进行蛋白浓度测定;

②若A测定大于1.0,建议将待测样本适当稀释后再进行测定;若A测定小于0.02,建议适当增加样本量后再进行测定,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。
