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 ...

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

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 ...

Biotin plays a vital role in preventing hair loss. A vitamin, it encourages hair growth. Deficiency of biotin leads to breakage of hair that results to hair loss.. Biotin and hair growth are directly related and therefore it is important that one incorporates biotin in their regular diet. Examples of foods that contain biotin include liver, egg yolk, brewers yeast, soybeans, oats, green peas, sunflower seeds, brown rice, bulgur, walnuts, cauliflower, avocado, legumes, mushrooms and fish.. However, biotin supplements are also recommended since it would take consumption of thousands of calories daily to reach the recommended level. Adding five to eight grams to your food twice everyday can go a long way in preventing hair loss.. Biotin is also referred to as Vitamin B7. Part of the Vitamin B complex, it is water-soluble. It is also worth noting that individuals with blood type A cant absorb B vitamins. Persons with acid reflux and heartburn tend to absorb biotin slowly and as a result, hair loss ...

Biotinidase deficiency is an autosomal recessive metabolic disorder in which biotin is not released from proteins in the diet during digestion or from normal protein turnover in the cell. This situation results in biotin deficiency. Biotin, also called vitamin B7, is an important water-soluble nutrient that aids in the metabolism of fats, carbohydrates, and proteins. Biotin deficiency can result in behavioral disorders, lack of coordination, learning disabilities and seizures. Biotin supplementation can alleviate and sometimes totally stop such symptoms. Signs and symptoms of a biotinidase deficiency can appear several days after birth. These include seizures, hypotonia and muscle/limb weakness, ataxia, paresis, hearing loss, optic atrophy, skin rashes (including seborrheic dermatitis and psoriasis), and alopecia. If left untreated, the disorder can rapidly lead to coma and death. Biotinidase deficiency can also appear later in life. This is referred to as late-onset biotinidase deficiency. ...

3-Methylcrotonyl-CoA carboxylase deficiency (MCCC2-related) is a pan-ethnic, autosomal recessive disease caused by pathogenic variants in the MCCC2 gene. These variants impair the ability of the enzyme 3-methylcrotonyl-CoA carboxylase to break down proteins that contain the amino acid leucine. Presentation in childhood or early infancy is characterized by feeding difficulties, vomiting and diarrhea, excessive fatigue, and hypotonia. If detected early, the condition can be managed with a low-protein diet. If untreated, this disorder can eventually cause developmental delay, seizures, and coma. However, most individuals with this condition remain asymptomatic into adulthood. Life expectancy depends on the severity of presentation. No clear genotype-phenotype correlation has been noted..

Excess intake of biotin is excreted in the urine no toxicity symptoms have been reported. Biotin works with some other B vitamins, such as folic acid, pantothenic acid vitamin B5, and vitamin B12. However, no solid evidence indicates that people supplementing with biotin also need to take these other vitamins. Symptoms of pantothenic acid or zinc deficiency have been reported to be lessened with biotin, though people with these deficiencies should supplement with the nutrients in which they are deficient. Researchers have speculated that biotin and alpha lipoic acid may compete with each other for absorption or uptake into cells but little is known about the importance of these interactions in humans. There is one report of a 76-year-old woman who developed a life-threatening condition eosinophilic pleuropericardial effusion while taking 10 mg of biotin per day and 300 mg of pantothenic acid per day. However, it is not clear whether the vitamins caused the problem. Certain medicines may interact ...

Mate Pair Library Sequencing enables the generation of libraries with inserts from 2 to 5 kb in size. These long-insert Paired-End libraries are useful for a number of applications, including De NovoSequencing, genome finishing, and structural variant detection. Combining data generated from Mate Pair library sequencing with that from short-insert paired-end reads provides a powerful combination of read lengths for maximal genomic sequencing coverage across the genome. Following DNA fragmentation, 2-5 Kb fragments are end-repaired with biotin labeled dNTPs. The DNA fragments are circularized, and non-circularized DNA is removed by digestion. Circular DNA is fragmented and fragments biotin labels (corresponding to the ends of the original DNA ligated together) are affinity purified. Purified fragments are end-repaired and ligated to Illumina Paired-End sequencing adapters. Additional sequences complementary to the flow cell oligonucleotides are added to the adapter sequence with tailed PCR ...

Abstract : In Escherichia coli, binding of the hexameric Rho protein to naked C-rich Rut (Rho utilization) regions of nascent RNA transcripts initiates Rho-dependent termination of transcription. Although the ring-shaped Rho factor exhibits in vitro RNA-dependent ATPase and directional RNA-DNA helicase activities, the actual molecular mechanisms used by Rho to disrupt the intricate network of interactions that cement the ternary transcription complex remain elusive. Here, we show that Rho is a molecular motor that can apply significant disruptive forces on heterologous nucleoprotein assemblies such as streptavidin bound to biotinylated RNA molecules. ATP-dependent disruption of the biotin-streptavidin interaction demonstrates that Rho is not mechanistically limited to the melting of nucleic acid base pairs within molecular complexes and confirms that specific interactions with the roadblock target are not required for Rho to operate properly.. ...

Streptavidin is a protein that has similar binding properties to egg white avidin. It is isolated from streptomyces avidinii. Streptavidin has a molecular weight of 60 kDa and has 4 subunits. Each subunit can bind one molecule of biotin. Biotin is a water-soluble vitamin. Streptavidin has an extremely high binding affinity (Kd=10-15) for biotin. It has proven useful in the detection of antigens coupled with biotinylated secondary antibodies. There are several advantages when using streptavidin versus an avidin complex (ABC).In contrast to avidin, streptavidin is not glycosylated and is therefore uncharged at neutral pH (6.5 versus 10). This lowers nonspecific background staining. Streptavidin also lacks carbohydrate side chains that may be another cause of non-specific background. Another key advantage of streptavidin is the significant increase in sensitivity (probably due to less steric hindrance), thus facilitating an increase in overall binding capacity. Finally, streptavidin-enzyme conjugates are

We describe in this study whether the gold nanoparticle (AuNP) surface-functionalized with PEG, biotin, paclitaxel (PTX) and rhodamine B linked beta-cyclodextrin (β-CD) (AuNP-5´) can be useful as a theranostic agent for cancer therapy without the cytotoxic effect on normal cells. Prior to surfacefunctionalizing AuNPs, the cytotoxicity of the nanoparticles was evaluated, followed by their cytocompatibility. PTX, an anti-cancer agent, formed inclusion complexations with β-CD conjugated AuNPs, and effectively released from the AuNP-2´ surface-functionalized with PEG, beta-cyclodextrin (β-CD) and paclitaxel (PTX) using the intracellular glutathione (GSH) level (10 mM). Two types of AuNP-4 surfacefunctionalized with PEG and rhodamine B linked β-CD and AuNP-5 surface-functionalized PEG, biotin and rhodamine B linked β-CD were used for evaluating their specific interaction on cancer cells such as HeLa, A549 and MG63. These were also tested against normal NIH3T3 cell, determining that the AuNP-5 ...

Biotin is a coenzyme in the metabolism of fatty acids and leucine, and it plays a role in gluconeogenesis.Biotin is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids. It plays a role in the citric acid cycle, which is the process by which biochemical energy is generated during aerobic respiration. Biotin not only assists in various metabolic reactions but also helps to transfer carbon dioxide. Biotin may also be helpful in maintaining a steady blood sugar level. Biotin is often recommended for strengthening hair and nails. As a consequence, it is found in many cosmetics and health products for the hair and skin, though it cannot be absorbed through the hair or skin itself. ...

20-plate (plates NOT included). Monoclonal antibody to mouse interleukin 4 (IL-4). Rat IgG|sub|1. Biotinylated monoclonal antibody to mouse interleukin 4 (IL-4). Rat IgG|sub|1. The usefulness of sandwich ELISAs (enzyme-linked immunosorbent assays) in cytokine biology is evident from the many reports published on this subject. The assay requires two antibodies (either mono- or polyclonal antibodies) that bind with high affinity to different sites on the cytokine molecule. One of the antibodies is immobilized to the wells of a 96-well microtiter plate. This so-called capture or coating antibody functions to selectively immobilize the cytokine from crude protein preparations. The second antibody (detection antibody) is labeled with biotin and binds to a different site on the cytokine molecule. Biotin allows the antibody to interact with streptavidin molecules. By using HRP (horseradish peroxidase)-labeled streptavidin, the cytokine can now quantitatively be determined by enzymatic conversion of a HRP

Biotinidase (BTD), a ubiquitous mammalian cell enzyme, is present in high levels in the serum, liver, and kidneys. Its primary enzymatic function is to cleave the vitamin biotin (also known as coenzyme R, vitamin H, or vitamin B7) from the organic compound biocytin.

Background Comparative analysis of the cellular biology of the microvasculature in different tissues requires the availability of viable primary endothelial cells (ECs). This study describes a novel method to isolate primary ECs from healthy organs, repair blastemas and tumors as examples of non-proliferating and proliferating benign and malignant tissues and their functional characterization. Methodology/Principal Findings Single cell suspensions from hearts, lungs, repair blastemas and tumors were incubated consecutively with an anti-CD31 antibody and magnetic micro-beads, coupled to a derivative of biotin and streptavidin, respectively. Following magnetic bead separation, CD31-positive ECs were released by biotin-streptavidin competition. In the absence of micro-beads, ECs became adherent to plastic surfaces. ECs from proliferating repair blastemas and tumors were larger and exhibited higher expression densities of CD31, CD105 and CD102 compared to those from non-proliferating normal tissues such as

This test is based on the principles of the immunoblot method. Various allergens are attached to the surface of nitrocellulose membranes in separate lines depending on the configuration of the panel. Allergen-specific IgE antibodies react with the appropriate allergens, if they are present in the patients samples. In a second step biotin-conjugated anti-human IgE antibodies bind to the attached antibodies. During a third incubation step the biotin binds to a streptavidin peroxidase conjugate. In a final incubation step the peroxidase turns the colorless substrate tetramethylbenzidine (TMB) into a bluish purple final product. After each individual incubation a washing step follows to remove unbound material. The intensity of the blue color is proportional to the amount of allergen-specific antibodies in the patients serum.. The sample is evaluated with a common 3D color flatbed scanner validated by R-Biopharm in combination with the software RIDA qLine® Soft. The color intensities of the ...

Dear everone, I am a research asssitant working in Cincinnati Childrens Hospital Research Foundation. I am currently doing dual-label FISH (Fluorecent Insitu Hybridization). I choosed the following schema: 1. dig labeld mRNA probe of gene1---------mouse anti-dig(Roche)---------Goat anti mouse with HRP(Molecular Biology)------Tyramide Signal Amplification (Molecular Biology) 2. biotin labeld mRNA probe of gene2------------strepavidin-HRP (Jacson Immuno)------Tyramide Signal Amplification (Molecular Biology) The first one (dig) gave me nice staining, but the second one (strepavidin) always gave high background. I know the biotin labeled probe is good, since when I use this probe tested with mouse-anti-bio antibody, then followed by Goat-anti-mouse-HRP second antibody, it works beautifully. So, the problem could be biotin-avidin problem. Did anyone experience same problem when doing FISH? Appreciate it!

N2 - The use of biotin or biotin-containing reagents is an essential component of many protein purification and labeling technologies. Owing to its small size and high affinity to the avidin family of proteins, biotin is a versatile molecular handle that permits both enrichment and purity that is not easily achieved by other reagents. Traditionally, the use of biotinylation to enrich for proteins has not required the detection of the site of biotinylation. However, newer technologies for discovery of protein-protein interactions, such as APEX and BioID, as well as some of the click chemistry-based labeling approaches have ...
