过氧化氢酶（Catalase, CAT, EC 1.11.1.6）是一种常见的抗氧化酶，可催化过氧化氢（H₂O₂）分解为水和氧气，普遍存在于含有细胞色素系统的好氧细胞中。过氧化氢对细胞具有高度毒性，其积累会导致DNA、蛋白质和脂质等细胞靶标发生氧化损伤，从而诱发突变和细胞死亡。过氧化氢酶通过清除细胞内的H₂O₂，防止氧化损伤的发生。目前，过氧化氢酶在氧化应激相关疾病中的作用已得到广泛研究。 本试剂盒利用过氧化氢酶的过氧化物酶功能测定其活性。在适宜浓度的H₂O₂存在下，过氧化氢酶催化甲醇反应生成甲醛；甲醛与显色剂反应生成有色产物，该产物在540 nm处具有特征吸收峰。样本中的过氧化氢酶活性与吸光度值（OD₅₄₀）成正比。
Catalase (CAT, EC 1.11.1.6) is a common antioxidant enzyme that catalyzes the decomposition of hydrogen peroxide (H₂O₂) to water and oxygen. It is ubiquitously present in aerobic cells containing cytochrome systems. Hydrogen peroxide is highly toxic to cells; its accumulation can cause oxidative damage to cellular targets such as DNA, proteins, and lipids, thereby inducing mutations and cell death. Catalase prevents oxidative damage by scavenging intracellular H₂O₂. Currently, the role of catalase in oxidative stress-related diseases has been extensively studied. This kit utilizes the peroxidase activity of catalase to determine its activity. In the presence of an appropriate concentration of H₂O₂, catalase catalyzes the reaction of methanol to generate formaldehyde. The formaldehyde then reacts with a chromogenic reagent to form a colored product, which exhibits a characteristic absorbance peak at 540 nm. The catalase activity in the sample is directly proportional to the absorbance value (OD₅₄₀).
