Product Information
Alcohol Dehydrogenase (ADH) Activity Assay Kit
-20℃ Dry Ice Transportation
  • 检测样本量:50 Samples
  • 主要检测设备及配套:紫外分光光度计/1 mL 石英比色皿(d=10 mm)
  • 预计测定时间:4 h (50 Samples)
  • 试剂储存条件:按照标签要求储存

Detection Principle
乙醇脱氢酶能够催化NADH还原乙醛生成乙醇和NAD+,NADH在340 nm处具有特征吸收峰,通过吸光值降低速率即可表征乙醇脱氢酶的活性。
  • 检测方法: NADH速率法
  • 检测波长: 340 nm
  • 信号响应: 递减型
Notices

①样本应尽量保持新鲜,采样后建议尽快完成测定;

②粗酶液制备过程建议在冰上进行,切勿使用液氮处理样本,且提取后需当天完成检测,严禁冷冻保存,反复冻融对乙醇脱氢酶稳定性有较大影响;

③粗酶液不能用于蛋白浓度测定,若需要使用蛋白浓度计算结果,需另取样本使用PBS或生理盐水按照相同比例,单独提取后再进行蛋白浓度测定;

④试剂二配制后有效期较短,为便于试验安排,附赠一瓶试剂二作为备用,每瓶均可满足至少50个样本的测定;

⑤若吸光值大于3.0,请确认比色皿是否为石英比色皿(Q);

⑥若A1测定大于1.5或∆A大于1.0,建议将粗酶液使用蒸馏水适当稀释后再进行测定;若∆A小于0.02,建议适当增加样本量或延长酶促反应时间(延长5-10 min)后再进行测定,计算时相应修改;

⑦准确在15 s和75 s处完成吸光值测定,以保证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。
