辣根过氧化物酶，简称HRP，HRP是一种单链多肽，含有4个二硫桥。它是一种糖蛋白，含有18％的碳水化合物。该碳水化合物组成包括半乳糖，阿拉伯糖，木糖，岩藻糖，甘露糖，甘露糖胺，半乳糖胺，这取决于特定的同功酶。 它的分子量（～44 kDa）包括分子量（33,890道尔顿）的多肽链，血红素加Ca2 +（700道尔顿），碳水化合物（约9,400道尔顿）。至少有7种HRP的同工酶存在。辣根过氧化物酶的等电点范围从3.0 - 9.0。 单位定义 one unit will form 1.0mg of purpurogallin from pyrogallol in 20sec at pH6.0 at 20degc. 辣根过氧化物酶是目前使用最广泛的一种标记酶，用来标记抗体或其它蛋白质，既能用于定位检测，也能用于定量测定。 辣根过氧化物酶（HRP）的从辣根根（Amoracia RUSTICANA）中分离。它是用于生物化学中的应用，如western印迹，ELISA和免疫组化。辣根过氧化物酶是用来放大弱信号，增加被探测的目标分子，如蛋白质。它通常被用于确定葡萄糖和溶液中的过氧化物的量。它也被用于在烟曲霉快速药敏测定。 HRP is a single chain polypeptide containing four disulfide bridges. It is a glycoprotein containing 18% carbohydrate. The carbohydrate composition consists of galactose, arabinose, xylose, fucose, mannose, mannosamine, and galactosamine depending upon the specific isozyme. Its molecular weight (~44 kDa) includes the polypeptide chain (33,890 Daltons), hemin plus Ca2+ (~700 Daltons), and carbohydrate (~9,400 Daltons). At least seven isozymes of HRP exist. The isoelectric point for horseradish peroxidase isozymes ranges from 3.0 - 9.0. Horseradish peroxidase is isolated from horseradish roots (Amoracia rusticana) and belongs to the ferroprotoporphyrin group of peroxidases. unit definition one unit will form 1.0mg of purpurogallin from pyrogallol in 20sec at pH6.0 at 20degc. Horseradish peroxidase (HRP) is isolated from horseradish roots (Amoracia rusticana) and belongs to the ferroprotoporphyrin group of peroxidases. It is used in biochemistry applications such as western blots, ELISA and Immunohistochemistry. Horseradish peroxidase is used to amplify a weak signal and increase detectability of a target molecule, such as a protein. It is commonly used to determine amounts of glucose and peroxides in solution. It has been used in an aspergillus fumigatus rapid susceptibility assay.

辣根过氧化物酶与底物孵育时，产生一种着色、荧光或发光标记的分子的衍生物，以便可以定量。辣根过氧化物酶已被证明抑制cydAB突变，使其突变水平稍微降低。已知其抑制剂是叠氮化钠，氰化物，L-胱氨酸，重铬酸盐，亚乙基硫脲，羟基胺，硫化物，钒酸，对氨基苯甲酸，和Cd2+, Co2+, Cu2+, Fe3+, Mn2+, Ni2+, 和 Pb2+离子。
