单胺氧化酶（MAO，EC 1.4.3.4）是催化单胺类物质氧化脱氨反应的酶，存在于细胞线粒体外膜上，主要分布于脊椎动物的各种器官（特别是分泌腺、脑、肝脏）中，在无脊椎动物及豆类芽等植物中亦有分布，但含量较低。本试剂盒采用比色法测定MAO活性：MAO催化单胺类底物脱氨生成相应的醛和过氧化氢（H₂O₂）；在过氧化物酶（POD）催化下，H₂O₂与4-氨基安替比林（4-AAP）等显色体系反应，生成红色醌亚胺化合物，该产物在510 nm处具有特征吸收峰。通过测定该波长下吸光值的增幅，结合标准曲线即可精准计算样品中MAO的酶活力大小。
Monoamine oxidase (MAO, EC 1.4.3.4) is an enzyme that catalyzes the oxidative deamination of monoamine substances. It is located on the outer membrane of mitochondria and is mainly distributed in various organs of vertebrates (especially secretory glands, brain, and liver). It is also found in invertebrates and plants such as bean sprouts, but at relatively low levels. This kit employs a colorimetric method for the determination of MAO activity: MAO catalyzes the deamination of monoamine substrates to generate the corresponding aldehydes and hydrogen peroxide (H₂O₂). In the presence of peroxidase (POD), H₂O₂ reacts with the chromogenic system containing 4-aminoantipyrine (4-AAP) to form a red quinone imine compound, which exhibits a characteristic absorbance peak at 510 nm. By measuring the increase in absorbance at this wavelength and referencing a standard curve, the MAO enzyme activity in the sample can be precisely calculated.
