多胺氧化酶（PAO，EC 1.5.3.3）广泛存在于动物、植物及微生物中，催化多胺氧化生成醛，其活性与核酸和蛋白质合成密切相关，并与植物逆境生理响应有一定关联。本试剂盒采用比色法测定PAO活性：PAO催化多胺底物氧化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）及酚类显色剂发生氧化偶联反应，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，即可精准计算样品中PAO的酶活力大小。
Polyamine oxidase (PAO, EC 1.5.3.3) is widely distributed in animals, plants, and microorganisms. It catalyzes the oxidation of polyamines to generate aldehydes. Its activity is closely associated with nucleic acid and protein synthesis, and is also related to the physiological responses of plants to environmental stress. This kit employs a colorimetric method for the determination of PAO activity: PAO catalyzes the oxidation of polyamine substrates to produce the corresponding aldehydes and hydrogen peroxide (H₂O₂). In the presence of peroxidase (POD), H₂O₂ undergoes an oxidative coupling reaction with 4-aminoantipyrine (4-AAP) and a phenolic chromogenic reagent 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, the PAO enzyme activity in the sample can be precisely calculated.
