一般說明

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。

單位定義

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。

分析報告

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。

Atherosclerosis and vasculitis both feature inflammation mediated by neutrophil-endothelial cell (EC) contact. Neutrophil myeloperoxidase (MPO) can disrupt normal EC function, although the mechanism(s) by which MPO is transferred to ECs are unknown. We tested the hypothesis that close, β2 integrin-dependent
