产品说明 一般描述 亲和素是一种同源四聚体蛋白(68kDa)，是从鸡蛋蛋白中获得的。这种鸡蛋蛋白和生物素紧密结合。因此，亲和素-生物素系统用于免疫分析，检测组织中抗原位置。使用亲和素-生物素免疫分析增强了技术的灵敏度，能够检测出少量的抗原。 应用 亲和素蛋白用于一项分析中，该分析使用官能化氙作用检测生物素-亲和素结合的生物传感器。使用80nmol的鸡蛋白。 包装 1, 2, 5 mg in glass bottle 单位定义 一单位能够结合1.0 μg d-生物素。 制备说明 亲和纯化 免责声明 除非我们的产品目录或产品附带的其他公司文档另有说明，否则我们的产品仅供研究使用，不得用于任何其他目的，包括但不限于未经授权的商业用途、体外诊断用途、离体或体内治疗用途或任何类型的消费或应用于人类或动物。 基本信息

| A8706 | Sigma-Aldrich | Avidin from egg white | recombinant, expressed in corn, ≥12 units/mg protein (E | 2649.62元/5 MG; | 咨询 | ||||||||||||||||||||||||||||||||||||||
产品说明 一般描述 Avidin is a homotetrameric glycoprotein found in the egg white of birds, reptiles and amphibians. Each subunit is 16 kDa, singly glycosylated and binds to a molecule of biotin with greater affinity and specificity. Recombinant avidin from corn is similar to avidin from egg white in terms of properties like isoelectric point (pI) and antigenic properties except for the molecular weight. Avidin from corn has low molecular weight than chicken egg-derived avidin. This might be due to less complex glycosylation composition in plants. Commercial production of avidin from corn has certain advantages in terms of availability of greater biomass and avoiding the co-purification of animal virus. 应用 Avidin forms an extremely strong complex with d-biotin (Kd ~ 10-15). This activity has made both avidin and biotin extremely useful labels in immunochemical methods of detection and quantitation. 包装 5 mg in glass bottle 单位定义 One unit will bind 1.0 μg of d-biotin. 制备说明 亲和纯化 基本信息

产品说明 一般描述 Avidin is a tetrameric glycoprotein and an anti-nutrient found in the eggs of all oviparous vertebrates. It constitutes 0.05–0.5% of the total protein in hen eggs. Avidin structure contains eight orthogonal antiparallel β-strands, a single disulfide bond, and a carbohydrate side chain. 应用 Avidin, Egg White has been used as a blocking agent in protein-binding assays. It has also been used to form avidin-biotin linkage to conjugate gemcitabine onto microbubbles for drug delivery to in vivo model. 包装 10, 100 mg in Plastic ampoule 生化/生理作用 Avidin can be used as a label for antibodies, fluorescent dyes, proteins,, and other molecules of interest to biochemists. The high binding affinity of avidin to biotin (vitamin H) causes the unavailability of biotin to microorganisms, which leads to the inhibition of their proliferation. This feature of avidin contributes to its antimicrobial property and affects biotin absorption in the body, resulting in vitamin B7 deficiency. 警告 Toxicity: Standard Handling (A) 单位定义 One unit is defined as the amount of avidin that will bind 1 µg D-biotin at pH 8.9. 重悬 Following reconstitution, store in the refrigerator (4°C). Stock solutions are stable for up to 6 months at 4°C. Avoid freeze/thaw cycles. 法律信息 CALBIOCHEM is a registered trademark of Merck KGaA, Darmstadt, Germany 基本信息
