背景資料

TFP-dPEG ? 12-生物素酶抗性生物素，產(chǎn)品編號(hào)QBD-10204，是一種經(jīng)修飾以抵抗生物素酶水解的水溶性生物素化試劑(EC www.example.com)。該產(chǎn)品將生物素酰基-2-氨基丁酸與中等長(zhǎng)度、單分子量、離散聚乙二醇(dPEG ?)接頭的2，3，5，6-四氟苯基(TFP)酯結(jié)合。TFP-dPEG ? 12-生物素酶抗性生物素保留了生物素對(duì)抗生物素蛋白和鏈霉抗生物素蛋白的典型高親和力，但也阻斷了生物素酶對(duì)生物素的作用。該產(chǎn)品可用于組織樣品的ELISA和抗體預(yù)靶向等應(yīng)用，其中內(nèi)源性生物素酶可回收生物素。

產(chǎn)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.
