产品介绍
在评估前半抗原的皮肤致敏潜力时,使用了来自Sigma的酶。它也已用于显示过氧化物酶(PO)活性及其热稳定性与游离Ca2+离子的可用性相关。辣根过氧化物酶(HRP)分离自辣根中(Amoracia rusticana)。 它可用于生物化学应用,如蛋白质印迹、ELISA和免疫组织化学。 辣根过氧化物酶可用于扩增弱信号并增加靶分子(例如蛋白质)的可检测性。 产品P6140已用于检测低密度脂蛋白(LDL)。应用: 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。 Horseradish peroxidase is isolated from horseradish roots ( Amoracia rusticana ) and belongs to the ferroprotoporphyrin group of peroxidases. 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 Ca 2+ (~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. Application: Horseradish peroxidase (HRP) is isolated from horseradish roots ( Amoracia rusticana ). 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 . Product P6140 has been used to detect low density lipoprotein (LDL) . The enzyme from Sigma has been used while assessing the skin sensitization potential of pro-haptens. It has also been used to show that peroxidase (PO) activity and its heat stability correlate with the availability of free Ca 2+ ions.
生化机理
HRP易与过氧化氢(H 2 O 2 )结合,所得[HRP-H 2 O 2 ]配合物可氧化各种氢供体。最佳pH为6.0-6.5,酶在5.0-9.0的pH范围内最稳定。HRP可以通过几种不同的方法与抗体结合,包括使用戊二醛、高碘酸盐氧化、二硫键以及氨基和巯基定向交联剂。它比酶标签,β-半乳糖苷酶和碱性磷酸酶更小、更稳定。因此,它是最理想的标签。而且,糖基化使其非特异性结合较低。 它还用于测定溶液中的葡萄糖 和过氧化物 。已发现叠氮化钠、氰化物、L-胱氨酸、重铬酸盐、亚乙基硫脲、羟胺、硫化物、钒酸盐、对氨基苯甲酸、以及Cd 2+ 、Co 2+ 、Cu 2+ 、Fe 3+ 、Mn 2+ 、Ni 2+ 、铅 2+ 等离子可抑制其酶活性。当与底物一起孵育时,辣根过氧化物酶可产生标记分子的有色荧光或发光衍生物,从而进行定量 。 研究已显示辣根过氧化物酶可略微降低cydAB突变体中的抑制水平 。
