转氢酶（TH）位于线粒体的内膜上，又称为线粒体复合体六，催化 NADH+NADP⁺和 NAD⁺+NADPH 相互转化，调节线粒体NAD(H)和 NADP(H)平衡。把逆向反应称为 TH-2，催化 NADPH 和NAD⁺生成 NADP⁺和 NADH。该产品可检测动植物组织生物样本。在该试剂盒中，NADH 和 NADPH 均在 340 nm 有特征吸收，因此TH催化的转氢反应不能导致 340 nm 吸光度发生变化。用人工合成底物 3-乙酰吡啶腺嘌呤二核苷酸（APAD⁺）替代NAD⁺，TH-2催化APAD⁺还原生成 APADH，APADH 在 375 nm 有特征光吸收，测定 375 nm 光吸收的增加速率，来计算 TH-2 活性。
Transhydrogenase (TH) is located on the inner mitochondrial membrane, also known as mitochondrial Complex VI. It catalyzes the interconversion between NADH + NADP⁺ and NAD⁺ + NADPH, regulating the balance of NAD(H) and NADP(H) in mitochondria. The reverse reaction is termed TH-2, which catalyzes the conversion of NADPH and NAD⁺ to generate NADP⁺ and NADH. This product is suitable for detecting biological samples from animal and plant tissues. In this kit, both NADH and NADPH have characteristic absorption at 340 nm; therefore, the transhydrogenation reaction catalyzed by TH does not result in a change in absorbance at 340 nm. Using the synthetic substrate 3-acetylpyridine adenine dinucleotide (APAD⁺) as a substitute for NAD⁺, TH-2 catalyzes the reduction of APAD⁺ to generate APADH, which has a characteristic light absorption at 375 nm. The TH-2 activity is calculated by measuring the rate of increase in absorbance at 375 nm.
