背景资料

TFP-dPEG ® 12-生物素酶抗性生物素，产品编号QBD-10204，是一种经修饰以抵抗生物素酶水解的水溶性生物素化试剂(EC www.example.com)。该产品将生物素酰基-2-氨基丁酸与中等长度、单分子量、离散聚乙二醇(dPEG ®)接头的2，3，5，6-四氟苯基(TFP)酯结合。TFP-dPEG ® 12-生物素酶抗性生物素保留了生物素对抗生物素蛋白和链霉抗生物素蛋白的典型高亲和力，但也阻断了生物素酶对生物素的作用。该产品可用于组织样品的ELISA和抗体预靶向等应用，其中内源性生物素酶可回收生物素。

产品描述

TFP-dPEG®12-biotinidase-resistant biotin, product number QBD-10204, is a water-soluble biotinylation reagent modified to resist hydrolysis by biotinidase (EC 3.5.1.12). This product combines Biotinoyl-2-aminobutyric acid with the 2,3,5,6-tetrafluorophenyl (TFP) ester of a medium-length, single molecular weight, discrete polyethylene glycol (dPEG®) linker. TFP-dPEG®12-biotinidase-resistant biotin retains biotin’s typical high affinity for avidin and streptavidin but also blocks the action of biotinidase on biotin. This product is useful in applications such as ELISAs of tissue samples and antibody pretargeting, where endogenous biotinidase can recycle biotin.nBiotinidase is an amidohydrolase that recycles biotin in vivo by breaking the covalent bond between biotin and amino acids such as lysine (i.e., biocytin). Although necessary for healthy bodily function, biotinidase potentially creates problems when biotinylated proteins are used in serological assays, since endogenous biotinidase removes the biotin from these proteins.nDr. D. Scott Wilbur and colleagues at the University of Washington in Seattle developed biotinidase-resistant biotin in 2006 to facilitate in vivo antibody pretargeting. To improve the product’s water solubility and ability to reach the binding pocket of avidin, a medium-length amino-dPEG®12-propionic acid linker was conjugated to the biotinidase-resistant biotin and subsequently functionalized as an TFP ester.nLike our other dPEG® biotinylation products, TFP-dPEG®12-biotinidase-resistant biotin, QBD-10204, will not cause aggregation and precipitation of biomolecules to which it is conjugated, and the dPEG® spacer reduces non-specific binding. It is potentially beneficial for applications using serological fluids that contain endogenous biotinidase. Useful roles for TFP-dPEG®12-biotinidase-resistant biotin include the following:ntherapeutic applications such as antibody pretargeting with biotin-streptavidin systems;nsupramolecular constructs (e.g., nanoparticles) used in vivo that depend on biotin-(strept)avidin affinity to maintain structural integrity; and,nELISAs of serological fluids and tissue samples using biotin-(strept)avidin affinity.
