单胺氧化酶(Monoamine Oxidase，MAO)是一组催化多种单胺类化合物氧化脱氨的酶，属于细胞外酶，含有铜离子，分布于肝脏、肾脏等组织的线粒体内，其含量分布为肝脏＞心脏＞肾脏＞脑＞肺＞骨骼肌，血小板、胎盘中也含有MAO。线粒体中的MAO与膜紧密结合，仅少量为可溶性的，存在于细胞质中，血液和结缔组织中的MAO为水溶性。 该试剂盒的检测原理是待测样品在MAO作用下，氧化底物苄胺生成苄醛，后者经催化反应生成醛苯腙呈棕红色，通过酶标仪检测470nm处吸光度，根据标准曲线即可测出MAO活力。本产品仅用于科研领域，不宜用于临床诊断或其他用途。
Monoamine Oxidase (MAO) is a group of enzymes that catalyze the oxidative deamination of various monoamine compounds. As an extracellular enzyme containing copper ions, MAO is primarily located within the mitochondria of tissues such as the liver and kidneys. Its distribution in terms of concentration follows the order: liver > heart > kidney > brain > lung > skeletal muscle. MAO is also present in platelets and the placenta. Within mitochondria, MAO is tightly bound to the membrane, with only a small soluble fraction found in the cytoplasm. The MAO present in blood and connective tissues is water-soluble. The detection principle of this kit is based on the oxidation of the substrate benzylamine by MAO in the sample, generating benzaldehyde. The benzaldehyde is subsequently catalyzed to form a brown-red colored aldehyde phenylhydrazone. By measuring the absorbance at 470 nm using a microplate reader and comparing it to a standard curve, the MAO activity can be determined.
