Identification of three distinct receptor binding sites of murine interleukin-11. (1/2828)

Interleukin-11 (IL-11) is a member of the gp130 family of cytokines. These cytokines drive the assembly of multisubunit receptor complexes, all of which contain at least one molecule of the transmembrane signaling receptor gp130. A complex of IL-11 and the IL-11 receptor (IL-11R) has been shown to interact with gp130, with high affinity, and to induce gp130- dependent signaling. In this study, we have identified residues crucial for the binding of murine IL-11 (mIL-11) to both the IL-11R and gp130 by examining the activities of mIL-11 mutants in receptor binding and cell proliferation assays. The location of these residues, as predicted from structural studies and a model of IL-11, reveals that mIL-11 has three distinct receptor binding sites. These are structurally and functionally analogous to the previously defined receptor binding sites I, II, and III of interleukin-6 (IL-6). This supports the hypothesis that IL-11 signals via the formation of a hexameric receptor complex and indicates that site III is a generic feature of cytokines that signal via association with gp130.  (+info)

Adhesion energy of receptor-mediated interaction measured by elastic deformation. (2/2828)

We investigated the role of receptor binding affinity in surface adhesion. A sensitive technique was developed to measure the surface energy of receptor-mediated adhesion. The experimental system involved a functionalized elastic agarose bead resting on a functionalized glass coverslip. Attractive intersurface forces pulled the two surfaces together, deforming the bead to produce an enlarged contact area. The Johnson-Kendall-Roberts (JKR) model was used to relate the surface energy of the interaction to the elasticity of the bead and the area of contact. The surface energies for different combinations of modified surfaces in solution were obtained from reflection interference contrast microscopy (RICM) measurements of the contact area formed by the bead and the coverslip. Studies with surfaces functionalized with ligand-receptor pairs showed that the relationship between surface energy and the association constant of the ligand binding has two regimes. At low binding affinity, surface energy increased linearly with the association constant, while surface energy increased logarithmically with the association constant in the high affinity regime.  (+info)

Molecular biology of biotin attachment to proteins. (3/2828)

Enzymatic attachment of biotin to proteins requires the interaction of a distinct domain of the acceptor protein (the "biotin domain") with the enzyme, biotin protein ligase, that catalyzes this essential and rare post-translational modification. Both biotin domains and biotin protein ligases are very strongly conserved throughout biology. This review concerns the protein structures and mechanisms involved in the covalent attachment of biotin to proteins.  (+info)

Human biotinidase isn't just for recycling biotin. (4/2828)

For years, the major role of biotin has been as the coenzyme for four carboxylases in humans. Although there has been evidence that biotin might have other functions, none has been firmly established. The discovery that human serum biotinidase has biotinyl-transferase activity, in addition to biotinidase hydrolase activity, presents new possibilities for the role of biotinidase in biotin metabolism. Specific transfer of biotin to histones by biotinidase provides a possible explanation for why biotin is found in the nucleus and the nature of its role in the regulation of protein transcription. Future studies will help to determine the functions of biotinidase in biotin metabolism and in disease states.  (+info)

Cellular uptake of biotin: mechanisms and regulation. (5/2828)

This review describes our knowledge of biotin transport in the small intestine of humans and other mammals and presents recent findings in the area. Previous studies have shown that biotin transport across the brush border membrane of the small intestinal absorptive cells occurs via a carrier-mediated, Na+ gradient-dependent, electroneutral mechanism. Exit of biotin out of the enterocyte, i.e., transport across the basolateral membrane, also occurs via a carrier-mediated process, but the process is Na+ independent and electrogenic. Recent studies from our laboratory have shown that the uptake process of biotin in Caco-2 cells, a human-derived cultured intestinal epithelial cell line, are under the cellular regulation of both a protein kinase C- and a Ca/calmodulin-mediated pathway. In addition, the uptake process is shared by another water-soluble vitamin, pantothenic acid. For the first time, other recent studies have detected the existence of a Na+-dependent, carrier-mediated mechanism for biotin uptake at the apical membrane of colonocytes, which could theoretically mediate absorption of the biotin synthesized by colonic microflora. This system was again found to be shared by pantothenic acid, which is also synthesized by the normal microflora of the large intestine.  (+info)

Advanced analysis of biotin metabolites in body fluids allows a more accurate measurement of biotin bioavailability and metabolism in humans. (6/2828)

In previous studies, the bioavailability of biotin in humans was estimated from the recovery of biotin in urine; urinary biotin was measured by microbial growth assays or assays of avidin-binding activity. These assays underestimate concentrations of biotin metabolites, which originate from beta-oxidation, sulfur oxidation or a combination. We have developed an HPLC/avidin-binding assay that is specific for biotin and its metabolites. With the use of the HPLC/avidin-binding assay, TLC and derivatization with p-dimethylaminocinnamaldehyde, we have identified and quantitated biotin and metabolites in urine from six healthy adults. Of that total, biotin accounted for 32+/-12%, bisnorbiotin for 52+/-15%, bisnorbiotin methyl ketone for 7.9+/-5.8%, biotin-d,l-sulfoxide for 4.0+/-3.2% and biotin sulfone for 3.6+/-1.9%. After intravenous administration of 18.4 micromol of biotin, the urinary excretion of biotin metabolites increased 21-130 times above baseline values. Because the biliary excretion of biotin is quantitatively minor (1.9+/-0.2% of an intravenous [14C]biotin dose in rats), intravenously administered biotin is not exposed to intestinal microorganisms. Thus we conclude that biotin metabolites in human urine originate from biotin catabolism in human tissues rather than biotin catabolism by intestinal microorganisms. With the use of the HPLC/avidin-binding assay, we estimated the bioavailability of biotin in adults from the urinary excretion of biotin and metabolites after ingestion of 2.1, 8.2 and 81.9 micromol of biotin. These data provide evidence that biotin is nearly completely absorbed.  (+info)

Biotin status: which are valid indicators and how do we know? (7/2828)

Although estimated average requirements for biotin have been proposed, the human requirements for biotin in specific populations and at various ages remain uncertain, in part because indicators of biotin status have not been validated. With the use of improved methods for measuring biotin and metabolites, a recent study indicated that decreased urinary excretion of biotin and bisnorbiotin is an early and sensitive indicator of biotin deficiency, but decreased serum concentration of biotin is not. Increased urinary excretion of 3-hydroxyisovaleric acid (3-HIA), a leucine metabolite that is excreted in increased quantities with deficiency of the biotin-dependent enzyme beta-methylcrotonyl-CoA carboxylase, is also an early and sensitive indicator of biotin deficiency. When these indicators were assessed longitudinally in 13 pregnant women, biotin excretion was not significantly decreased early in pregnancy but did decrease significantly from early to late pregnancy. Excretion of 3-HIA was abnormally increased in about three-fourths of the women studied in both early and late pregnancy. Thus, each indicator detected biotin deficiency late in pregnancy, but assessment of biotin status for the two indicators conflicted early in pregnancy. Preliminary results from a trial assessing response of 3-HIA excretion to biotin treatment indicate that biotin status is indeed impaired both early and late in pregnancy.  (+info)

Mapping binding domains of kininogens on endothelial cell cytokeratin 1. (8/2828)

Human cytokeratin 1 (CK1) in human umbilical vein endothelial cells (HUVEC) is expressed on their membranes and is able to bind high molecular weight kininogen (HK) (Hasan, A. A. K., Zisman, T., and Schmaier, A. H. (1998) Proc. Natl. Acad. Sci. U. S. A. 95, 3615-3620). New investigations have been performed to demonstrate the HK binding domain on CK1. Four overlapping recombinant (r) CK1 proteins were produced in Escherichia coli by a glutathione S-transferase gene fusion system. Biotin-HK specifically bound to rCK128 and rCK131 in the presence of Zn2+ but not to Deleted1-6rCK131. Recombinant CK128 and rCK131 also inhibited biotin-HK binding to HUVEC with IC50 of 0.4 and 0.5 microM, respectively. Alternatively, rCK114 and Deleted1-6rCK131 did not inhibit binding at concentrations >/=1 microM. Seven sequential 20 amino acid peptides of CK1 were prepared to cover the protein coded by exons 1-3. Only the first peptide (GYG20) coded by exon 1 significantly inhibited HK binding to HUVEC with an IC50 of 35 microM. Fine mapping studies isolated two overlapping peptides also coded by exon 1 (GPV15 and PGG15) that inhibited binding to HUVEC with IC50 of 18 and 9 microM, respectively. A sequence scrambled peptide of PGG15 did not block binding to HUVEC and biotin-GPV20 specifically bound to HK. Peptides GPV15 and PGG15 also blocked prekallikrein activation on endothelial cells. However, inhibition of PK activation by peptide PGG15 occurred at 10-fold lower concentration (IC50 = 1 microM) than inhibition of biotin-HK binding to HUVEC (IC50 = 10 microM). These studies indicate that HK binds to a region of 20 amino acids coded by exon 1 on CK1 which is carboxyl-terminal to its glycine-rich amino-terminal globular domain. Furthermore, HK binding to CK1 modulates PK activation on HUVEC.  (+info)

Holocarboxylase synthetase (HCS, human) and BirA (Escherichia coli) are biotin protein ligases that catalyze the ATP-dependent attachment of biotin to apocarboxylases. Biotin attachment occurs on a highly conserved lysine residue within a consensus sequence (Ala/Val-Met-Lys-Met) that is found in carboxylases in most organisms. Numerous studies have indicated that HCS and BirA, as well as biotin protein ligases from other organisms, can attach biotin to apocarboxylases from different organisms, indicating that the mechanism of biotin attachment is well conserved. In this study, we examined the cross-reactivity of biotin attachment between human and bacterial biotin ligases by comparing biotinylation of p-67 and BCCP87, the biotin-attachment domain fragments from human propionyl-CoA carboxylase and E. coli acetyl-CoA carboxylase, respectively. While BirA has similar biotinylation activity toward the two substrates, HCS has reduced activity toward bacterial BCCP87 relative to its native substrate, p-67.
U.S., Feb. 27 -- ClinicalTrials.gov registry received information related to the study (NCT03034707) titled Interference of Biotin Supplementation in Biotin-streptavidin Platforms for Hormone Testing on Jan. 17. Brief Summary: The B vitamin biotin is widely available as an over the counter supplement, often advertised and used to promote health of hair, skin and nails. Commercially available over the counter biotin supplements contain dose ranges up to 10 mg/day (ie 333 times higher than the recommended dietary allowance). The biotin molecule is also sometimes used as part of the lab technology to measure hormone and protein levels in the blood. It is possible that high doses of ingested biotin may interfere with accurate hormone or protein measurement using biotin related in vitro measurement systems. Such interference, if present, could lead to misdiagnosis. The study will analyze laboratory levels obtained with streptavidin-biotin assay systems while ingesting biotin in currently available ...
FIG. 5. Effects of the l-glutamate-producing condition of biotin limitation on l-glutamate production in AJ11024. Wild-type (solid circles) and AJ110214 (open circles) cells were cultured under biotin-limited conditions. Biotin concentrations are shown along the x axis. For biotin-limited conditions, seed cultures were prepared with 10, 30, 60, 100, and 300 μg of biotin liter−1, and 1 ml was inoculated into 20 ml of the main medium lacking biotin so that biotin was depleted during the main cultures. For biotin-rich conditions, a seed culture was prepared in 300 μg of biotin liter−1, and 1 ml was inoculated into 20 ml of the main medium containing 300 μg of biotin liter−1. The biotin concentration was calculated by dividing the total amounts of biotin supplied to the seed and main cultures by the volume of the main culture. The specific l-glutamate production rate (A), the specific glucose consumption rate (B), and the l-glutamate yield (C) are shown. Specific rates were calculated ...

An experiment was conducted to evaluate the effect of different levels of biotin on productive performance of Holstein dairy cow. In this experiment a change-over design with twelve multiparous cows, three rations and three periods was employed. Ingredients of the basal diet were alfalfa hay (24%) corn silage (16%) and concentrate (60%) on dry matter basis. The experimental diets 1 to 3 contained 0, 10 and 20 mg of biotin per day, respectively. The rations were fed to cows as Total Mixed Rations (TMR), but biotin was top-dressed on the a.m. allotment of ration. The cows were individually ad libitum and milked three times per day. Daily milk yielded was recorded and samples of the milk were taken once per week for determination of milk composition. Blood were taken in end of each period. Dry Matter Intake (DMI) and milk yield of cows were not affected by biotin. Also milk compositions were not affected by biotin. The average of Fat Corrected Milk (FCM) yield for 4% fat for rations contain 0, 10 and 20 mg
Biotin (vitamin H or vitamin B7) is the essential cofactor of biotin-dependent carboxylases, such as pyruvate carboxylase and acetyl-CoA carboxylase. Mammals cannot synthesize biotin, while in bacteria, fungi, and plants it is synthesized from pimelate thioester through different pathways. In E. coli and many organisms, pimelate thioester is derived from malonyl-ACP. The pathway starts with the methylation to malonyl-ACP methyl ester, followed by the fatty acid chain elongation cycle to form pimeloyl-ACP methyl ester, which is then demethylated to form pimeloyl-ACP [MD:M00572]. Pimeloyl-ACP is converted to biotin through the final four steps in the biotin bicyclic ring assembly, which are conserved among biotin-producing organisms [MD:M00123]. In B. subtilis, biotin is derived from pimeloyl-ACP formed by oxidative cleavage of long-chain acyl-ACPs [MD:M00573]. Some bacteria synthesize biotin from pimeloyl-CoA derived from pimelate [MD:M00577]. Biotin is covalently attached to biotin-dependent ...

Biotin is one vitamin that has multiple benefits. With so many benefits, it would be hard to not go out and get some extra Biotin for yourself.. It does a great job of providing extra energy. This is because of the enzymes that work with carbs, fats, and protein metabolism need Biotin. Processes that go on in the deepest levels of our digestive system rely on Biotin. This is especially true when it comes to working with Amino Acids.. As mentioned above, Biotin can help with weak nails. If you are experiencing nails that crack or chip often, you might want to consider getting you some Biotin. It does not take much either to ensure stronger and healthier nails.. One of the most commonly known benefits of Biotin is its ability to strengthen and grow your hair. If you are not getting enough Biotin, it can lead to hair loss.. As mentioned above, pregnancy and Biotin are closely related. The vitamin is needed during pregnancy. The reason this is so important is that some studies have shown a lack of ...
Sensor performance of a dielectric filled silicon bulk acoustic resonator type label-free biosensor is verified with biotin-streptavidin binding interactions as a model system. The mass sensor is a micromachined silicon square plate with a dielectric filled capacitive excitation mechanism. The resonance frequency of the biotin modified resonator decreased 315 ppm when exposed to streptavidin solution for 15 min with a concentration of 10−7 M, corresponding to an added mass of 3.43 ng on the resonator surface. An additional control is added by exposing a bovine serum albumin (BSA)-covered device to streptavidin in the absence of the attached biotin. No resonance frequency shift was observed in the control experiment, which confirms the specificity of the detection. The sensor-to-sensor variability is also measured to be 4.3%. Consequently, the developed sensor can be used to observe in biotin-streptavidin interaction without the use of labelling or molecular tags. In addition, biosensor can be used

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 ...
Acetyl-CoA carboxylase is a biotin-dependent, multifunctional enzyme that catalyzes the first committed step in fatty acid synthesis. The Escherichia coli enzyme is composed of a homodimeric biotin carboxylase, biotinylated biotin carboxyl carrier protein (BCCP), and an α2β2 heterotetrameric carboxyltransferase. Catalysis by acetyl-CoA carboxylase proceeds via two half-reactions. In the first half-reaction, biotin carboxylase catalyzes the ATP-dependent carboxylation of biotin, which is covalently attached to BCCP, to form carboxybiotin. In the second half-reaction, carboxyltransferase transfers the carboxyl group from carboxybiotin to acetyl-CoA to form malonyl-CoA. All biotin-dependent carboxylases are proposed to have a two-site ping-pong mechanism where the carboxylase and transferase activities are separate and do not interact. This posits two hypotheses: either biotin carboxylase and BCCP undergo the first half-reaction, BCCP dissociates, and then BCCP interacts with carboxyltransferase to
Regulation of the expression of the gene(s) coding for the 78-kD, biotin-containing subunit of [beta]-methylcrotonyl-coenzyme A carboxylase (MCCase) was investigated in different organs of tomato (Lycopersicon esculantus) plants. The specific activity of MCCase is highest in extracts from roots, followed in descending order by ripe and ripening fruits, stems, and leaves. The specific activity is 10-fold higher in roots than in leaves. However, the steady-state levels of the 78-kD subunit of MCCase and its mRNA are approximately equal in both roots and leaves. Instead, the difference in MCCase activity between these two organs is directly correlated to the biotinylation status of the enzymes biotin-containing subunit. Thus, the lower activity of MCCase in leaves is attributed to the reduced biotinylation of the biotin-containing subunit of the enzyme. Consistent with this model, a pool of nonbiotinylated enzyme is present in leaves, whereas the nonbiotinylated enzyme is undetectable in roots. ...
The attachment of biotin to various chemical sites, called biotinylation, can be used as an important laboratory technique to study various processes including DNA transcription and replication. Biotin itself is known to biotinylate histones, but is not found naturally on DNA.. Biotin binds very tightly to the tetrameric protein streptavidin, with a dissociation constant Kd in the order of 10-15 mol/L (Bonjour 1977, Green 1975) or 4x10-14 (Holmberg et al. 2005). Holmberg et al. (2005) note that the biotin-streptavidin system is the strongest noncovalent biological interaction known. This is often used in different biotechnological applications. Holmberg et al. showed how to utilize high temperatures to efficiently break the interaction without denaturation of the streptavidin.. In the biology laboratory, biotin is sometimes chemically linked, or tagged, to a molecule or protein for biochemical assays. The specificity of the biotin-streptavidin linkage allow use in molecular, immunological, and ...

Since favorable images of infection are obtained with radio-labeled nonspecific IgG, streptavidin has been considered as an alternative protein in this investigation. The advantage of streptavidin is that once localized it may be targeted with radiolabeled biotin. Studies were conducted in a mouse model with an Escherichia coli infection in one thigh. Indium-111-labeled streptavidin showed equivalent localization to the infection as that obtained with 111In-labeled polyclonal nonspecific IgG, however blood levels with streptavidin were lower at all time points; consequently, target-to-blood ratios were improved. Pretargeting with unlabeled streptavidin followed 3 hr later with 111In-labeled biotin showed equivalent localization in the target and reduced activity in all organs sampled. As such, infected thigh-to-normal thigh ratios were improved 3-fold for pretargeting versus either labeled IgG or streptavidin. Improvements in infected thigh-to-liver and blood ratios were greater than 8-fold. Only in the

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
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.
TY - JOUR. T1 - Epigenetic regulation of chromatin structure and gene function by biotin. AU - Hassan, Yousef I.. AU - Zempleni, Janos. PY - 2006/7/6. Y1 - 2006/7/6. N2 - Covalent modifications of histones are a crucial component of epigenetic events that regulate chromatin structures and gene function. Evidence exists that distinct lysine residues in histones are modified by covalent attachment of the vitamin biotin, catalyzed by biotinidase and holocarboxylase synthetase. Biotinylation of histones appears to be conserved across species. The following biotinylation sites were identified using both MS and enzymatic biotinylation of synthetic peptides: K9, K13, K125, K127, and K129 in histone H2A; K4, K9, and K18 in histone H3; and K8 and K12 in histone H4. Evidence was provided that biotinylated histone H4 is enriched in pericentromeric heterochromatin, and that biotinylation of histone H4 participates in gene silencing, mitotic condensation of chromatin, and the cellular response to DNA damage. ...
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 ...
The CD19 CAR Detection Reagent (Biotin) has been developed for the detection of transduced T cells that are engineered to express CD19-specific chimeric antigen receptors (CAR) on the cell surface, which recognize human CD19 antigen. The CD19 CAR Detection Reagent (Biotin) is an antigen based detection reagent conjugated to biotin. It contains a recombinantly expressed fusion protein consisting of the human CD19 extracellular domains and a specifically mutated human IgG1 Fc region. The engineered CD19 CAR T cells can be detected via the recognition of the CD19 protein, and identified by flow cytometry via anti-biotin fluorochromes. The mutated human IgG1 Fc region of the CD19 CAR Detection Reagent abolishes their binding to Fcγ receptors. This allows for background-free analysis and eliminates the need for additional blocking steps, such as using a FcR blocking reagent. - Ireland

Biotin is an essential vitamin in plants and mammals, functioning as the carbon dioxide carrier within central lipid metabolism. Bacterial pimeloyl-CoA synthetase (BioW) acts as a highly specific substrate-selection gate, ensuring the integrity of the carbon chain in biotin synthesis. BioW catalyzes the condensation of pimelic acid (C7 dicarboxylic acid) with CoASH in an ATP-dependent manner to form pimeloyl-CoA, the first dedicated biotin building block. Multiple structures of Bacillus subtilis BioW together capture all three substrates, as well as the intermediate pimeloyl-adenylate and product pyrophosphate (PPi), indicating that the enzyme uses an internal ruler to select the correct dicarboxylic acid substrate. Both the catalytic mechanism and the surprising stability of the adenylate intermediate were rationalized through site-directed mutagenesis. Building on this understanding, BioW was engineered to synthesize high-value heptanoyl (C7) and octanoyl (C8) monocarboxylic acid-CoA and C8 ...
Står dette på nettsiden: Biotin Alone Is Not Enough to Correct Poor Horn Quality in Most Cases Its only one of many nutrients needed by the adult horse. In fact, the adult horse is said to have no dietary requirement for biotin unless under stress conditions such as intense work, traveling, being stabled for long periods or being fed a low-quality diet. And even under these conditions, biotin deficiency is relatively rare, and is usually accompanied by many dietary deficiencies. Biotin Supplementation Horses which respond to biotin supplementation alone (approximately 5% of those with poor-quality horn) show large holes in the outermost layer of the wall when viewed under a microscope. The inner layers of the wall were usually not affected. However; our recent research indicates that an increased amount of biotin helps the hoof in the presence of laminitis. Methionine, Proline, Glycine and Glutamine are some of the major building blocks of healthy connective tissue, or collagen. Copper and ...
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.. ...
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 ...
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 ...
Fluorescent Dyes , Biotins and Streptavidins , Streptavidin, recombinant; Streptavidin is a nonglycosylated, tetrameric protein, with each subunit able to bind a single molecule of the vitamin biotin. Streptavidin-biotin bond is the strongest known non-covalent interaction with Kd ~10-15 M. Because streptavidin lacks any carbohydrate modification and has a near-neutral pI, it has the advantage of much lower nonspecific binding than avidin. Streptavidin is broadly used in various applications such as immunoassays, histochemistry, FISH (Fluorescence In Situ Hybridization), flow cytometry, microarrays and blot analysis.
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 ...
Recent work in this laboratory has shown that hydnocarpic acid (HA), a principal constituent of chaulmoogra oil, inhibits multiplication in vitro of a number of mycobacterial species. This activity of HA was not shared by several straight-chain fatty acids and by dihydrochaulmoogric acid. A study of the interaction of HA with biotin has been undertaken, based on a structural analogy between biotin and the cyclopentenyl fatty acid. The multiplication of a strain of Mycobacterium intracellulare susceptible to 2 μg of HA/ml was measured turbidimetrically in Dubos medium, in the presence and absence of biotin and several other compounds. Biotin and, to a lesser extent, adenine plus guanine, palmitic acid, and linoleic acid antagonized growth inhibition by HA. Desthiobiotin, thioctic acid, and succinic acid did not block inhibition of bacterial multiplication by HA. HA may act by blocking the coenzymatic activity of biotin, or it may inhibit microbial biotin synthesis. Resumption of multiplication ...
