General description
辣根过氧化物酶是从辣根（Amoracia rusticana）中分离出来的，属于过氧化物酶的铁原卟啉基团。HRP是含有四个二硫键的单链多肽。它是一种含有18%碳水化合物的糖蛋白。碳水化合物由半乳糖、阿拉伯糖、木糖、岩藻糖、甘露糖、甘露糖胺和半乳糖胺组成，具体取决于特定同工酶。其分子量（约44 kDa）包括多肽链（33,890道尔顿）、氯化血红素加Ca2+ （约700道尔顿）和碳水化合物（约9,400道尔顿）。至少存在7种HRP同工酶。 辣根过氧化物酶同工酶的等电点范围为3.0-9.0。
Analysis Note
RZ(Reinheitszahl)是指溶于去离子水中的酶(0.5–1.0 mg/ml)的吸光度比值A403/A275 。 它是血红素含量的量度，而不是酶活性。 即使是RZ值较高的制剂也可能具有较低的酶活性。
Other Notes
一个连苯三酚单元将在20℃、pH 6.0条件下，在20秒内从连苯三酚形成1.0mg的红棓酚。

Anti-neutrophil cytoplasmic antibody-associated (ANCA-associated) small vessel necrotizing vasculitis is caused by immune-mediated inflammation of the vessel wall and is diagnosed in some cases by the presence of myeloperoxidase-specific antibodies (MPO-ANCA). This multicenter study sought to determine whether differences in ANCA
