一般說明
异柠檬酸脱氢酶 (IDH) 催化异柠檬酸转化为 α-酮戊二酸。在真核生物中，IDH 有三种同工酶，线粒体 IDH2 和 IDH3 以及细胞质/过氧化物酶体 IDH1。所有三个 IDH 家族成员的酶活性均需要存在二价阳离子（Mg 2 + 或 Mn 2 + ）和电子接受辅助因子 NADP + （IDH1 和 IDH2）或 NAD + (IDH3)。在某些癌症如胶质母细胞瘤、急性髓性白血病和结肠癌中发现 IDH1 和 IDH2 突变导致新形成层酶活性。该新活性显示底物特异性发生变化，导致 α-酮戊二酸转化为 2-羟基戊二酸。IDH 家族成员的突变也与 Ollier 病和 Maffucci 综合征有关。
應用
异柠檬酸脱氢酶 (IDH) 活性测定试剂盒用于测定样品中异柠檬酸脱氢酶的活性。
特點和優勢
与高通量处理系统兼容。
適合性
适用于测定生物样本（包括组织、细胞和血清）中的异柠檬酸脱氢酶 (IDH)（NAD +-依赖性、NADP + 依赖性或两种 IDH）活性
原則
异柠檬酸脱氢酶活性测定试剂盒为测定多种样品中 NADP + 依赖性、NAD + 依赖性或 NADP + 和 NAD + 依赖性 IDH 活性提供了一种简单直接的方法。在酶反应中使用异柠檬酸盐作为底物测定 IDH 活性，得到比色产物 (450 nm) 与存在的酶活性成正比。一个单位的 IDH 是在 37°C、pH 8.0 时每分钟生成 1.0 μmol NADH 或 NADP 的酶量。

Oxidative stress-induced neuronal cell damage is a crucial factor in the pathogenesis of mitochondria-associated neurological diseases. Therefore, elimination of overproduction of mitochondrial reactive oxygen species (mtROS) may be a potential strategy for prevention and treatment of neurological diseases. In the

Rationale: Recurrent and metastatic cancers often undergo a period of dormancy, which is closely associated with cellular quiescence, a state whereby cells exit the cell cycle and are reversibly arrested in G0 phase. Curative cancer treatment thus requires therapies that

Background: Mitochondrion is an important metabolic and energetic organelle that regulates several cellular processes. Mitochondrial dysfunction has been related to liver diseases including hepatocellular carcinoma. As a result, the energetic demand is not properly supplied and mitochondrial morphologic changes have
