产品介绍 Avidin is a tetrameric or dimeric biotin-binding protein produced in the oviducts of birds, reptiles and amphibians deposited in the whites of their eggs. In chicken egg white, avidin makes up approximately 0.05% of total protein (approximately 1.8 mg per egg). The tetrameric protein contains four identical subunits (homotetramer), each of which can bind to biotin (Vitamin B7, vitamin H) with a high degree of affinity and specificity. In its tetrameric form, avidin is estimated to be between 66–69 kDa in size.Ten percent of the molecular weight is attributed to carbohydrate content composed of four to five mannose and three N-acetylglucosamine residues. The carbohydrate moieties of avidin contain at least three unique oligosaccharide structural types that are similar in structure and composition.

亲和素是一个四聚体或二聚体的生物素结合蛋白在鸟类的输卵管产生，爬行动物和两栖动物的蛋的蛋白沉积。在鸡蛋白中，抗生物素蛋白约占总蛋白的0.05%（大约每卵1.8毫克）。四聚体蛋白含有四个相同的亚基（四），每一个都可以结合生物素（维生素B，维生素H）具有高度的亲和力和特异性。在它的四聚体形式，亲和素估计要在66–69 kDa的大小，分子量百分之十是由于碳水化合物含量由四至五的甘露糖和三个N-乙酰葡糖胺残基。抗生物素蛋白的碳水化合物部分至少含有三种结构和成分相似的独特寡糖结构类型。
