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+,进一步通过1-mPMS的递氢作用,还原WST-1生成水溶性甲臜,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若A测定或∆A测定超出标准吸光值线性范围:高于最高值建议将待测样本使用蒸馏水适当稀释后再进行测定;低于最低值建议制备更高浓度样本后再进行测定,计算时相应修改;

②试剂二配制后有效期较短,为便于试验安排,附赠一支试剂二作为备用,每支均可完成至少50个样本的检测;

③提取液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;

④准确在规定时间点完成吸光值测定,以确保检测结果的准确性和重复性;若样本较多可分批进行检测,以确保组间反应时间一致;

⑤反应体系中试剂不能按比例配制为混合液使用,必须按反应体系顺序依次加入;

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。
