过氧化物酶(peroxisome,POD)是以过氧化氢为电子受体催化底物氧化的酶,主要存在于细胞的过氧化物酶体中,以铁卟啉为辅基,可催化过氧化氢,氧化酚类和胺类化合物,具有消除过氧化氢和酚类、胺类毒性的双重作用,该酶属于细胞木质素合成途径中间的关键酶,研究该酶可以探讨多种生物细胞发育过程中木质素沉积的代谢机理,为减少水果石细胞含量提高其品质提供依据。 该试剂盒检测原理是以愈创木酚(又称2-甲氧基酚)作为底物,在酶促反应的最适条件下采用每隔一定时间测定产物生成量的方法,于酶标仪470nm处测定吸光度,以吸光度变化所需酶量进行计算,主要用于植物组织的裂解液或匀浆液样品中内源性的过氧化物酶活性,尤其适用于测定水果中过氧化物酶活性。该试剂盒仅用于科研领域,不适用于临床诊断或其他用途。
Peroxidase (POD) is an enzyme that uses hydrogen peroxide as an electron acceptor to catalyze the oxidation of substrates. It is mainly located in cellular peroxisomes, uses iron porphyrin as a prosthetic group, and catalyzes the oxidation of phenolic and amine compounds by hydrogen peroxide, playing a dual role in eliminating the toxicity of hydrogen peroxide, phenols, and amines. This enzyme is a key enzyme in the lignin synthesis pathway in plants; studying it allows for investigation into the metabolic mechanisms of lignin deposition during the developmental processes of various biological cells, providing a basis for reducing stone cell content in fruits and improving their quality. The detection principle of this kit is as follows: Using guaiacol (also known as 2-methoxyphenol) as a substrate, under optimal conditions for the enzymatic reaction, the method measures the amount of product generated at fixed time intervals. The absorbance is measured at 470 nm using a microplate reader, and the enzyme activity is calculated based on the amount of enzyme required for the change in absorbance. This kit is primarily used for determining endogenous peroxidase activity in plant tissue lysates or homogenate samples, and is particularly suitable for measuring peroxidase activity in fruits. This kit is intended for research use only and is not for use in diagnostic procedures.
