Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

一般描述

研究领域:癌症

应用

克氏梭菌心肌黄酶已用于:
  • 鳃细胞乳酸脱氢酶测定。[1]
  • 浸渍在试纸上进行甲酸脱氢酶测定。[2]
  • 在电子受体存在下氧化β-NADH或β-NADPH的各种测定。
  • 苯醌还原过程中生成半醌。[3]
  • 评估培养肌肉细胞中的葡萄糖摄入情况。[4]
  • 乳酸脱氢酶细胞毒性检测。[5]

生化/生理作用

心肌黄酶在电子受体(例如亚甲基蓝或2,6-二氯苯酚吲哚酚)存在下催化β-NADH或β-NADPH的氧化。 心肌黄酶对β-NADH或β-NADPH具有特异性。Straub的猪心脏酶可能具有天然心肌黄酶(β-NADH特异性)以及硫辛酸和硫辛酰胺脱氢酶活性。

单位定义

一个单位的心肌黄酶将在25℃、pH 7.5下每分钟氧化1.0微摩尔的β-NADH,并相应还原适当的电子受体。

外形

以含有海藻糖冻干粉形式提供。
