Polyclonal antibodies are a pool of antibodies originating from different B cells in a host animal that recognize more than one epitope on the same protein or antigen. In contrast, a monoclonal antibody is an antibody originating from a single B cell in a host animal that recognizes only one epitope or binding site on a protein or other antigen. Polyclonal antibodies are usually purified from the serum of an immunized host animal such as a rabbit, chicken or goat. Whereas monoclonal antibodies are usually purified from cell culture media supernatant from the growth of a hybridoma cell line. Monoclonal antibodies are divalent but monospecific. Polyclonal antibodies are also divalent but consist of a pool of antibodies with multiple epitope specificities.. ...

Monoclonal antibodies, shown here binding to a cell, are monospecific antibodies (these are antibodies that have an affinity for the same antigen) - mAB or moAb, as they are abbreviated, are the same because they are created by identical immune cells that are clones of a unique parent cell. Monoclonal antibodies are created to specifically bind to a substance so they can detect or purify that particular substance. In medications the non-proprietary drug name ends in -mab. Typically, monoclonal antibodies are produced by fusing myeloma cells with the spleen cells from a mouse and recently, as a result of advances, from rabbit B-cells. Monoclonals can be used as therapies for various serious diseases such as rheumatoid arthritis, multiple sclerosis and - Stock Image C009/4806

Enzyme-linked immunosorbent assay (ELISA), also known as an enzyme immunoassay (EIA), is a biochemical technique used mainly in immunology to detect the presence of an antibody or an antigen in a sample. In simple terms, in ELISA, an unknown amount of antigen is affixed to a surface, and then a specific antibody is applied over the surface so that it can bind to the antigen. This antibody is linked to an enzyme, and in the final step a substance is added that the enzyme can convert to some detectable signal, most commonly a colour change in a chemical substrate.. If an immunogen is injected into an animal, a number of cells will bind that antigen, so the antibody which appears in the bloodstream. The antibodies will have arisen from several clones of cells and are different, so the antibody in bloodstream is a polyclonal antibody. Polyclonal antibody contain different antibodies bind to different antigen. ...
The monoclonal Anti-His antibody facilitates the fast and convenient detection of His-tagged fusion proteins, expressed in either prokaryotic or eukaryotic cells. The conjugated antibody allows fast and convenient analysis of His-tagged fusion proteins. Conjugation of the Anti-His antibody to HRP simplifies Western blot or ELISA analysis as the incubation with secondary antibodies becomes dispensable. Fluorochorme-conjugated Anti-His antibodies enable direct flow cytometry and fluorescent microscopy analyses, while indirect fluorescent labeling of His fusion protein expressing cells is possible with the biotin-conjugated antibody. After incubation the Anti-His-HRP antibody can be directly detected using commercially available chemiluminescent reagents. The monoclonal Anti-His antibody specifically recognizes proteins that contain a polyhistidine tag at their N- and C-terminus. However, the Anti-His-HRP (C-term.) antibody shows higher sensitivity and specificity for C-terminal His-tagged proteins. -

Monoclonal antibodies (Mabs), produced in the laboratory, are derived from the antibodies that the human body produces in the natural course to fight intruders that threaten health. The discovery of these antibodies have radically transformed our understanding of how diseases progress, and how they can be more quickly, accurately, and cheaply diagnosed, and thus substantially expanded the horizons of treatment for more than 50 major ailments. The importance of Mabs can be estimated from the fact that today a majority of the most commercially-successful drugs are Mab-derived, and Mab-drugs are projected to clock sales of US$125 billion annually by 2020.. Mabs in Cancer Treatment Cancer is unarguably one of the fields where monoclonal antibodies have had the strongest impact. The biggest advantage of Mabs is that they are able to avoid the healthy cells while specifically targeting the cancer cells. This translates to the patient experiencing fewer side effects than conventional radiotherapy or ...

OBJECTIVE: To search for antibodies against neuronal cell surface proteins. METHODS: Using immunoprecipitation from neuronal cultures and tandem mass spectrometry, we identified antibodies against the α1 subunit of the γ-aminobutyric acid A receptor (GABAAR) in a patient whose immunoglobulin G (IgG) antibodies bound to hippocampal neurons. We searched 2,548 sera for antibodies binding to GABAAR α, β, and γ subunits on live HEK293 cells and identified the class, subclass, and GABAAR subunit specificities of the positive samples. RESULTS: GABAAR-Abs were identified in 40 of 2,046 (2%) referred sera previously found negative for neuronal antibodies, in 5/502 (1%) previously positive for other neuronal surface antibodies, but not in 92 healthy individuals. The antibodies in 40% bound to either the α1 (9/45, 20%) or the γ2 subunits (9/45, 20%) and were of IgG1 (94%) or IgG3 (6%) subclass. The remaining 60% had lower antibody titers (p = 0.0005), which were mainly immunoglobulin M (IgM) (p = 0.0025),

Supplementary MaterialsSupplementary information. of ERs as well as the efficacy of SERMs for PCa treatment exist, notably due to the use of ER antibodies lacking specificity and treatments with high SERM concentrations leading to off-target effects. To end this confusion, our objective was to study the impact of estrogenic and anti-estrogenic ligands in well-studied PCa models with appropriate controls, dosages, and ER subtype-specific antibodies. When using physiologically relevant concentrations of nine estrogenic/anti-estrogenic compounds, including five SERMs, we observed no significant modulation of PCa cell proliferation. Using RNA-seq and validated antibodies, we demonstrate that these PCa models do not express ERs. In contrast, RNA-seq from PCa samples from patients have detectable expression of ER. Overall, our study reveals that commonly used PCa models are inappropriate to study ERs and indicate that usage of alternative versions is vital to properly measure the roles from the ...

Eleven monoclonal antibodies directed against the subcomponent C1q of the first component of human complement, C1, were prepared and tested for binding to intact C1q and to the collagenous portion, the C1q stalks. All of the monoclonals bound well to the intact C1q. Eight out of the eleven exhibited strong binding to the collagenous stalks, while three bound very weakly, if at all, to the stalks and, thus, were presumed to bind to the pepsin-sensitive region which includes the C1q heads. For one of the latter monoclonals, this was confirmed by electron microscopy. Five of the monoclonals were purified by C1q affinity chromatography. When tested with C1 reassembled from its subunits, two of these purified monoclonal antibodies markedly enhanced the rate of spontaneous activation.
It is possible to produce a humanized antibody without creating a chimeric intermediate. "Direct" creation of a humanized antibody can be accomplished by inserting the appropriate CDR coding segments (responsible for the desired binding properties) into a human antibody "scaffold". As discussed above, this is achieved through recombinant DNA methods using an appropriate vector[3] and expression in mammalian cells. That is, after an antibody is developed to have the desired properties in a mouse (or other non-human), the DNA coding for that antibody can be isolated, cloned into a vector and sequenced. The DNA sequence corresponding to the antibody CDRs can then be determined. Once the precise sequence of the desired CDRs are known, a strategy can be devised for inserting these sequences appropriately into a construct containing the DNA for a human antibody variant.[10][11] The strategy may also employ synthesis of linear DNA fragments based on the reading of CDR sequences.. Alemtuzumab is an ...

Polyclonal, anti-idiotypic, rabbit antibodies have been raised against four murine monoclonal anti-morphine Fab fragments. The antibody preparations, after affinity purification, have been shown to contain an anti-paratypic fraction which reversibly inhibits morphine binding to the anti-morphine antibodies and to cellular opiate receptors. Using some of the unique properties of this system, for the first time cross-reactivities of anti-paratypic antibodies with the monoclonal anti-morphine IgGs have been examined including competition for the same binding sites by a classical opiate agonist/antagonist pair.
Our body has a unique method to fight aggressor foreign micro-organisms when they enter our body.. When any virus, fungus, or bacterium enters our body and starts meddling with our system, our body triggers this mechanism. As a result, our body immune system creates antibodies specific to that foreign substance.. They are basically proteins but all antibodies are not the same.. Bacteria, fungi, or viruses contain character specific proteins called antigens. Antigens are also found on non-living micro-particles such as toxins, snake venoms, pollen, bacterial toxins, chemicals, drugs, and foreign particles. That marks them apart from each other.. After the antibodies are created, the second step is triggered by our defense system. Now there is a fight between the newly generated antibodies and the interfering antigens. This goes on till our body is clear of all antigens or the antigens completely overwhelm the antibodies. But, complete surrender of the antibodies is an ideal condition.. The ...
Antibodies are a vital part of our immune system. These proteins bind to specific antigen proteins on the surface of foreign bodies such as bacteria and viruses in order to neutralize or disarm them. Since each antigen has a different shape, it requires a different antibody to attach to it. By tailoring antibodies to attach to proteins responsible for specific diseases, pharmaceutical companies seek to develop drugs that minimise side-effects caused by antibodies binding to the wrong targets. Researchers at Boehringer have been studying a molecule in an antibody and they found that it was unusually compact as a single crystal. The next step was to obtain structural information of the molecule in solution.. ...
Natural antibodies (NAbs) circulate in normal individuals in the absence of exogenous antigenic stimulation. In the mouse NAbs derive mainly from B-1 cells, a distinct B-cell subset found in the peritoneal and pleural cavities as well as the spleen. In contrast with B-2 cells, B-1 cells are positively selected against self-antigens. The repertoire of B-1 cell derived natural antibodies is characterized by a preferential usage of germline-encoded VH and VL genes, which lack N-region additions and is evolutionarily selected due to their importance for organisms survival and homeostasis. The natural antibody population rapidly recognizes and protects against pathogens that have not been encountered previously. On the other hand NAbs cross-react with several self-antigens and besides their role as first line defense against pathogens, it has been demonstrated they perform important
An antigen is a substance which is used to generate the production of antibodies. In the case of this PolyExpressTM package, this is either a native protein or peptide sequence. The origin of your target antigen is the type of organism that the protein or peptide sequence to be used as an antigen originally came from. An accession number is a unique identification given to a biological polymer sequence and may be found in protein databases such as UniProt. Peptides created through GenScripts OptimumAntigen™ design program have many advantages over full proteins when it comes to antibody production. Our OptimumAntigen™ Design Tool combines the industrys most advanced algorithms with GenScripts time-tested expertise. Each peptide antigen is measured against several protein databases to confirm the desired antibody and epitope specificity. We guarantee a polyclonal antibody with ELISA titer of 1:32,000 or better for any host with the aid of our antigen design tool and unique antibody ...
Invaluable assistance in this task was provided by a monoclonal antibody, a special protein that identifies cell structures with a high degree of specificity. The antibody in question, which is known as AD5-10, binds specifically to the receptors that usually receive and transmit the TRAIL signal. In addition to studies, in which TRAIL itself is used as a therapeutic agent, so-called monoclonal antibodies are also being researched which, like AD5-10, bind to the TRAIL receptor. Yet they can only trigger a suicide signal if there is no resistance to TRAIL. AD5-10 is special, however, because, although it binds to the TRAIL receptor like the other monoclonal antibodies, it does not bind at the precise location where the TRAIL itself docks. Therefore, AD5-10 can arise bound to the receptor along with TRAIL, reports Prof. Krainer. Prof. Krainers team has proposed an interesting hypothesis that takes into account the unique binding site of AD5-10 to the receptor. It is possible that, due its ...
Purpose: : BVES is a transmembrane protein that regulates tight junction (TJ) and adherens junction (AJ) formation. Furthermore, disruption of BVES level induces phenotypic changes in human corneal epithelial (HCE) cells that are associated with increased wound healing. These observations led us to postulate that antibodies blocking BVES will induce increased corneal healing. Methods: : Rabbit polyclonal antibodies (Y666) against BVES extracellular region (aa 3-16) were generated. Cultured HCE cells and organ cultured mouse eyes were employed to determine the effects of these antibodies on cell adhesion (immunofluorescent staining), RhoA activation (Elisa assay), and mouse model corneal wound healing. Results: : The immunofluorescent staining on confluent HCE cells for BVES with Y666 reveals a cell membrane pattern of distribution, similar to staining with intracellular domain BVES antibodies (846). Furthermore, Y666 is capable of binding to BVES in live HCE cells. Following antibody treatment ...
