Aurora B Antibody BIOTIN

Application of Biotin-4-Fluorescein in Homogeneous Fluorescence Assays for Avidin, Streptavidin, and Biotin or Biotin Derivatives

Biotin-4-fluorescein (B4F) is a convenient molecular probe for (strept)avidin and for unlabeled biotin in homogeneous fluorescence assays. The primary standard is a 16 μM working solution of d-biotin which is used to titrate an aliquot

The Avidin-Biotin Complex (ABC) Method and Other Avidin-Biotin Binding Methods

These methods involve, at their core, the vitamin biotin and the protein avidin, which bind together irreversibly. By establishing a biotin link, through avidin, between the horseradish peroxidase enzyme and a secondary antibody reagent

生物素biotin

　　   　　维生素B复合体之一。是很多动植物生长发育所必需的物质。与维生素H，辅酶R、生物活素Ⅱb，微生物增殖因子S.W.X一样，天然存在的均为d异构体，L型没有生物学活性。在生物体内，它几乎都是作为生物素酶的辅基与蛋白质的赖氨酸的ε-氨基形成共价键。其生理作用主要是由生物素酶引起的固碳作用及羧基转移反应。通过丙酰辅 酶A羧化酶，乙酰辅酶A羧化酶，甲基丙二酸单酰CoA羧基转移酶等反应参与糖和脂肪的代谢。在这些酶促反应中形成的N-羧基生物
