Avidin is a basic charged glycoprotein present in the egg white and in some extent in tissues of various animals. Avidin is a homotetrameric protein that contains 4 identical subunits which bind to Biotin with high extent of affinity and specificity consisting of 128 amino acids and has a molecular mass of about 67K Daltons. Avidin-Biotin is a modified form of affinity purified avidin that combines the high affinity specific activity of the native egg white avidin to biotin molecule together with a very low background of the streptavidin produced by the bacteria Streptomyces avidinii.
Although thoroughly studied in terms of structural, biochemical and biophysical characteristics, the biological functions of avidins are not fully understood. Here, we expand the research on avidins by reporting xenavidin, the first avidin-like protein from a frog, which was identified as an expressed sequence tag (EST) from the Xenopus tropicalis genome project. Avidins appear to be conserved among egg-laying vertebrates [3, 4, 6] and are thought to have a role as defence proteins against microbial infections [43, 44]. Bird eggs contain egg yolk, the compartment for embryonic development, and the egg white that surrounds the egg yolk provides both nutrients and protection for the embryo. In frogs, the equivalent to egg white is called egg jelly [45]. The avidin content of egg jelly may have an important role in the embryonic development of frogs, a hypothesis that is also supported by recent studies within natural bird populations, in which the concentration of avidin in egg white appears to be ...
Background: Cell proliferation occurs not only in normal but also in cancer cells. Most of cell proliferation inhibition can be done by inhibiting the DNA synthesis, notably by intervening the formation of purine or pyrimidine. In purine de novo synthesis, it was assumed that biotin plays a role as a coenzyme in carboxylation reaction, one of the pivotal steps in the purine de novo pathways. The aim of this study was to see the avidin potency to bind biotin and inhibit mitosis.. Methods: Peripheral blood mononuclear cell (PBMC) was cultured in RPMI-1640 medium and stimulated by phytohemagglutinin (PHA) in the presence or absence of interleukin-2 (IL-2), with or without avidin. The effect of avidin addition was observed at 24, 48, and 72 hours for cell proliferation, viability, and cell cycle. Statistical analysis was done by one-way ANOVA.. Results: Avidin inhibited cell proliferation and viability in culture under stimulation by PHA with and without IL-2. Cell cycle analysis showed that avidin ...
The Fluorescent Avidin Kit contains 500g of three fluorescent avidin products: Fluorescein Avidin DCS, Texas Red Avidin D and AMCA Avidin D.
One of the most popular methods of noncovalent conjugation is to make use of the natural strong binding of avidin or its derivative streptavidin to biotin. Each avidin molecule contains a maximum of four biotin binding sites thereby increasing the strength of their interaction with biotin. Depending on the functionality present on the biotinylation compounds, specific reactive groups on antibodies may be modified to create a avidin binding site. Amines, carboxylates, sulfhydryls, and carbohydrate groups can be specifically targeted for biotinylation through the appropriate choice of biotin derivative.. Avidin is a glycoprotein found in egg whites that contains four identical subunits of 16,400 Da each. The subunits each contain one binding site for biotin also known as vitamin H. The biotin interaction with avidin is the strongest noncovalent affinity known, exhibiting a dissociation constant of about 1.3×10-15M. Tryptophan and lysine residues in each subunit are involved in forming the binding ...
The avidin-biotin system is a technique for studying the interaction between two biomolecules in an indirect manner, as follows: Biotin is chemically coupled to a binder molecule (e.g., a protein, DNA, hormone, etc.) without disturbing the interaction with its target molecule; avidin is then used to "sandwich" between the biotinylated binder and a reporter molecule or probe. This allows for a variety of tasks, including localization and identification of the binder or target molecule. Consequently, the avidin-biotin system can frequently replace radioactive probes. Together with Ed Bayer, Wilchek established the Avidin-biotin system as a powerful tool in biological sciences. Early in the 1970s, they exploited Avidin as a probe and developed new methods and reagents to biotinylate antibodies and other biomolecules. Today, the system is applied in research and diagnostics as well as medical devices and pharmaceuticals. Examples include western blot, ELISA, ELISPOT and pull-down assays.[12] More ...
Biotin Agarose Resin is used for purification or removal of avidin or streptavidin samples. Biotin is immobilized through a spacer arm by means of covalent binding that minimize leakage. The binding is very strong, making it suitable for non-reversible b
Abstract The avidin-biotin-peroxidase complex enzyme-linked immunosorbent assay (ABC-ELISA) and standard ELISA were used for the detection of Echinococcus granulosus antibody in sera of 101 patients operated on for hydatid disease, 40 patients with miscellaneous nonhydatid diseases, and 61 normal subjects. Sensitivity and specificity of the two procedures were comparable and the geometric mean antibody titer detected with ABC-ELISA was higher than with standard ELISA. The ABC-ELISA is a sensitive, specific, simple, and convenient method for diagnosing hydatidosis.
The ABC method is an indirect method of immunohistochemistry. It stands for the Avidin-Biotin Complex Method. Firstly, the tissue of interest is sectioned and is incubated with a primary antiserum that targets the antigen we would like to locate in the tissue section. An antiserum is a serum containing antibodies such as agglutinins and antitoxins. This antiserum is known as the primary antibody and is injected into the tissue to target the antigen and causes an antibody-antigen reaction. After the primary antibody is inserted. A secondary labeled antibody is added, namely a biotinylated antibody. The secondary antibody reacts with the first antibody and launches a large mass of biotin into the area in which the antigen is situated. The secondary antibody is reacts in an opposite manner to the primary antibody. The secondary antibody does not have the intention in reacting with the antigen. The addition of the avidin biotin enzyme complex causes binding to the secondary antibody. The avidin ...
Avidin and streptavidin reagents are powerful tools to detect or purify biotinylated proteins, nucleic acids, and other macromolecules.
1. The reaction between avidin and biotin was found to be exothermic, DeltaH being -20.3kcal./mole of biotin bound. The corresponding value of DeltaH for streptavidin was -23kcal./mole. 2. The heat evolved was independent of the pH (between 5 and 9), of the buffer (borate or ammonia) and of the fractional saturation of the avidin with biotin. 3. The entropy change for the reaction was zero, and it is suggested that the entropy increase to be expected from hydrophobic interactions was counterbalanced by a decrease in entropy accompanying the formation of buried hydrogen bonds. 4. Modification of the potential hydrogen-bonding sites of the imidazolidone ring led to a decreased heat output and a positive entropy of reaction.. ...

In biochemistry, biotinylation is the entire process of covalently attaching biotin to a protein, nucleic acid or other molecule. Biotinylation is quick, certain and is not likely to perturb the natural operate from the molecule due to the small dimension of biotin (MW = 244.31 g/mol). Biotin binds to streptavidin and avidin with an especially superior affinity, quick on-price, and higher specificity, and these interactions are exploited in many areas of biotechnology to isolate biotinylated molecules of desire. Biotin-binding to streptavidin and avidin is resistant to extremes of heat, pH and proteolysis, earning capture of biotinylated molecules attainable in numerous types of environments ...
2000 Da) were able to fill all three of the remaining avidin-binding sites, while only one molecule of biotinylated PEG5000 or stem cell factor bound to each avidin. The resulting biotin−avidin−biotin linkages were stable for prolonged periods under continuous perfusion, even in the presence of excess free biotin. Hematopoietic M07e cells bound to immobilized peptide ligands for α5β1 (cyclic RGD) and α4β1 (cylic LDV) integrins in a DPB-dose-dependent manner, with near-maximal binding to cylic LDV for surfaces containing 1% DPB. Multiple ligands were adsorbed in a controlled manner by incubating NeutrAvidin with the respective ligands in the desired molar ratio and then adding the resulting complexes to DPB-containing surfaces. Cell adhesion to surfaces containing both cylic LDV and cyclic RGD increased in an additive manner compared to that for the individual ligands. The bioactivity of adsorbed biotinylated stem cell factor was retained, as demonstrated by DPB-dose-dependent M07e cell ...
In the biotin-avidin method, cells are incubated first with biotin-conjugated monoclonal antibody and then subsequently incubated with fluorochrome-conjugated avidin. In the second antibody method, cells are incubated with an unconjugated monoclonal antibody followed by fluorochrome-conjugated goat anti-mouse Ig.. These sandwich techniques provide increased fluorescence intensity, which is valuable for microscopy. However, indirect methods can result in the formation of complexes that will artifactually stain Fc receptor-binding cells. The biotin-avidin method gives the least amount of artifactual staining particularly when streptavidin conjugates are used. Indirect methods will alter the proportionality between the amount of antigen and the fluorescence intensity per cell, therefore, these methods are not recommended for assessing the absolute number of antigenic determinants per cell. However, indirect methods can be used to determine the relative brightness differences between cell ...
Adenoviral vectors have great potential for use in gene therapy and genetic immunization. The targeting of Ad vectors to the relevant tissue and cell types in vivo could greatly improve their safety and performance by lowering the effective dosage required for therapeutic levels of gene expression. Redirection of Ad vector tropism will require physical modifications of the adenoviral capsid but direct genetic modification of the Ad capsid has so far been limited to small peptides. A novel system for the attachment of targeting ligands to the Ad capsid, based on the extremely strong avidin-biotin interaction, is described herein. The genetic insertion of a biotin acceptor peptide (BAP) into the fiber, protein IX, or hexon components of the Ad capsid has resulted in vectors that are metabolically biotinylated upon production in host cells. Avidin-dependent redirection of transduction through a variety of biotinylated ligands is greatly dependent on the nature of the biotinylated capsid protein. ...

N2 - The covalent binding of biotin to histones participates in heterochromatin formation, cell cycle progression and cellular response to DNA breaks. Biotinylation of histones appears to be a reversible process, but the identity of enzymes that remove biotin marks is largely unknown. Our long-term goal is to identify histone debiotinylases in human cells. Here we developed an avidin-based plate assay to quantify histone debiotinylase activities in nuclear extracts. This assay is an essential first step in purifying and identifying histone debiotinylases from human cells. Using this assay, we demonstrated that debiotinylation of histones depends on temperature and pH, consistent with enzyme catalysis. Experiments with purified histones, proteases and protease inhibitors provide evidence that removal of biotin ...
TY - JOUR. T1 - An equilibrium model of endothelial cell adhesion via integrin-dependent and integrin-independent ligands. AU - Chan, Bernard P.. AU - Bhat, Vinayak D.. AU - Yegnasubramanian, Srinivasan. AU - Reichert, William M.. AU - Truskey, George A.. PY - 1999/12/1. Y1 - 1999/12/1. N2 - Endothelial cell adhesion can be enhanced by supplementing integrin-mediated adhesion via fibronectin with the high-affinity avidin-biotin system in which biotin is covalently linked to membrane proteins and avidin binds to biotinylated surfaces (Bhat et al. J Biomed Mater Res 1998;41:377-85). An equilibrium model was extended to explain detachment of spreading cells following exposure to flow for this two ligand system. The two different receptor-ligand systems were treated as springs in parallel in which the equilibrium dissociation constant was a function of the separation distance of the cell from the surface. Flow experiments were performed to measure the endothelial cell adhesion strength as a function ...

N2 - The three-step pretargeting approach, based on the avidin-biotin system, has been shown to improve the target/non target ratio in radioimmunoscintigraphy. This pilot study was designed to assess the feasibility of applying the same strategy to radioimmunotherapy. Five patients, with advanced metastatic CEA positive carcinomas were studied. All patients received two cycles of therapy with an interval of 3 months in between. The protocol consisted of an i.v. injection of 10 mg of biotinylated anti-CEA antibody, followed 24h later by avidin: 3 mg as rapid bolus (chase effect) plus 50 mg in 100 ml of saline. Biotin-LC-DOTA (2.5 mg) was labelled with Y-90 and injected i.v. 24 h later. The injected ...

In the first part of this work, microfabricated Capillary Electrophoresis devices were integrated with microfabricated PCR devices for fast DNA amplification and separation., rapid on-chip amplification and separation of genes of interest was performed. A micro DNA extraction device using paramagnetic micro silica beads was consequently developed, subsequently a combined on-chip DNA extraction from a single drop of blood and PCR amplification were performed. In the second part of this work, micro array-based strategies for proteomics studies were developed. Two new strategies for site-specific immobilization of kinase substrates onto functionalized slides were developed: In addition, a novel fluorescent antibody-based detection was developed to rapidly screen for kinase substrate phosphorylation. Avidin-biotin is one of the strongest know non-covalent interaction, and by arraying C-terminal biotinylated proteins on avidin functionalized slides, a very stable array of functionally active proteins ...

Although ovarian cancer implants can be targeted using an avidin-3 rhodamineX complex, there are several reasons to consider alternative complexes. GmSA-20ROX is substantially less immunogenic compared with avidin, and GmSA has been used as the basis for a technetium-99m-labeled radiopharmaceutical to assess hepatic reserve in humans. Additionally, GmSA-20ROX binds target cells more rapidly and more efficiently than avidin due to its multivalency (7, 16). Because GmSA synthesis involves the conjugation of 23 d-galactosamines reacted with carboxyl groups rather than amino groups on an albumin molecule (7), there are multiple binding sites for the d-galactose receptor and the molecule has a favorably high isoelectric point (7, 16). Moreover, activation via dequenching of the rhodamineX after cellular internalization provides a generalizable platform for targeted fluorescent probes by exchanging the targeting moiety (5). We used the d-galactose receptor as a target in this study because it is ...

The cytokine ELISPOT (Enzyme-Linked ImmunoSPOT) assay is designed to enumerate cytokine-secreting cells in single cell suspensions of lymphoid tissue, central nerve system (CNS) tissue, bone marrow or preparations of peripheral blood mononuclear cells (PBMCs). The assay has the advantage of detecting only activated/memory T cells and has the ability to detect cytokine release in response to antigen by a single cell thereby permitting direct calculation of responder T cell frequencies. The high sensitivity and easy performance, allowing the determination of peptide-reactive T cells without prior in vitro expansion, makes the ELISPOT assay eminently well suited to monitor T cell responses. The higher sensitivity of ELISPOT in comparison to that of ELISA or intracellular staining is due to the plate-bound antibodies

Either a direct or an indirect assay principle can be chosen, and one can select from a large number of detection and labeling formats. Under certain conditions, one has to adapt a specific staining technique according to the needs of the tissue and the molecules under study. The principles of immunohistological staining can be also applied for the detection of target molecules other than antigens supposed that selective probes are available. With the experience of immunocytochemistry, a number of non-immunological affinity detection principles have become developped. For example, molecular affinity bindings of lectins and nucleic acids (in situ hybridization, FISH etc.) evolved from immunohistological detection principles. The detection formats include enzymatic and nonenzymatic labels, avidin-biotin principles, antibody-protein A bindings and other types of ligand bindings ...

Non-covalent binding of avidin to biotinylated erythrocytes results in complement-dependent haemolysis. Biotinylated erythrocytes, as well as native cells, are not lysed by complement. Complement activation requires a tight contact between avidin and the erythrocyte membrane, since avidin does not in itself activate complement and does not inhibit lysis of sensitized sheep erythrocytes. The efficiency of haemolysis depends on avidins surface density. When the avidin concentration in the reaction mixture is less than 15 micrograms/ml, erythrocyte lysis is not induced. However, the attachment of biotinylated antibodies to avidin-carrying erythrocytes decreases dramatically. Acylation of avidin with succinic anhydride strongly decreases its ability to induce complement-dependent haemolysis. However, the ability of avidin to cross-link the biotin-containing structures decreases after acylation. A 50% modification of avidin by succinic anhydride (pI about 7.0) allows preparation of ...
