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.

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 ...

Abstract All therapeutic antibodies and most vaccines critically depend on the ability of antibodies to specifically recognize particular antigens consequently detailed characterization of antibody antigen binding can provide invaluable information to understand and guide development Unfortunately due to the time and expense required atomic resolution structure determination is typically used sparingly late in a development process or for a small number of different antibodies or antigen variants We seek to enable earlier and larger scale but still detailed characterization and modeling of antibody antigen binding applicable to panels of antibodies that could result from screening polyclonal samples or engineered libraries along with panels of antigens that could result from attempts to understand and account for diversity across populations While not at atomic resolution our approach will still allow residue level localization of specific epitopes for specific antibodies as well as group level ...

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),

With the development of molecular cloning technology and the deep understanding of antibody engineering, there are diverse bispecific antibody formats from which to choose to pursue the optimal biological activity and clinical purpose. The single-chain-based bispecific antibodies usually bridge tumor cells with immune cells and form an immunological synapse because of their relatively small size. Bispecific antibodies in the IgG format include asymmetric bispecific antibodies and homodimerized bispecific antibodies, all of which have an extended blood half-life and their own crystalline fragment (Fc)-mediated functions. Besides retargeting effector cells to the site of cancer, new applications were established for bispecific antibodies. Bispecific antibodies that can simultaneously bind to cell surface antigens and payloads are a very ideal delivery system for therapeutic use. Bispecific antibodies that can inhibit two correlated signaling molecules at the same time can be developed to overcome inherent

Monoclonal antibodies are a unique class of biological agents that have been developed for autoimmune disease, antitumor and antiplatelet therapy to name a few. Antibodies produced by the body in response to an infection are polyclonal antibodies, meaning the antibodies produced are not identical. Monoclonal antibodies are immunoglobulins that are identical and bind to the same antigenic surface marker, thus the term targeted therapy. The naming of monoclonal antibodies is based on the target of the antibody (e.g. tumor, viral) and the source from which the antibody was produced (e.g. murine, human), followed by the mab suffix. While monoclonal antibodies have a wide therapeutic benefit, they have limitations including inability to cross the blood brain barrier and cost.. This presentation will review the history, types and immunogenicity of each type of monoclonal antibody. The nurse will understand the naming nomenclature of monoclonal antibodies and will be able to recognize the action of ...

Horse anti-human thoracic duct lymphocyte globulin (ATDLG) has been used successfully for the treatment of severe aplastic anemia, although not all lots have comparable efficacy. We have characterized the antibody specificities contained in one lot of Swiss ATDLG found to provide a response rate of 69% and another lot that provided only a 31% response rate. Antibody specificities were analyzed quantitatively by competitive inhibition assays with the use of a panel of fluorescein-conjugated murine monoclonal antibodies that recognize T cell antigens, common leukocyte antigens, and la-like antigens. Although there was wide variation in the amounts of individual antibody specificities within each lot, the effective lot of ATDLG contained an average of 2 1/2 times as much of each antibody specificity as the less effective lot. There were only two antibody specificities that differed remarkably from this pattern; and these deviations did not appear sufficient to account for the variation in ATDLG efficacy.

TY - JOUR. T1 - A human monoclonal antibody against HLA-Cw1 and a human monoclonal antibody against an HLA-A locus determinant derived from a single uniparous female. AU - Mulder, A. AU - Kardol, M J. AU - Uit het Broek, C M. AU - Tanke-Visser, J. AU - Young, Neil Thomas. AU - Claas, F H. PY - 1998/10/1. Y1 - 1998/10/1. N2 - Two human monoclonal antibodies (HuMAbs) with widely different HLA specificities were raised from a uniparous HLA-seropositive female. Screening against a large panel of serologically HLA-typed lymphocytes in the complement-dependent cytotoxicity test showed that one of these HuMAbs, VP6G3, was specific for HLA-Cw1, thereby constituting the first HuMAb against an HLA-C locus product. The second HuMAb, VP5G3, was directed against an HLA-A-encoded determinant shared by HLA-A11, -A25, -A26 and -A66. The epitopes responsible for binding were determined by comparing the aminoacid sequences and were pinpointed to the 6K/9F combination for HuMAb VP6G3, and 163R with a critical ...

Many monoclonal antibodies that react with the lacto-N-fucopentaose III (LNF III) antigenic determinant, Gal beta 1-4(Fuc alpha 1-3)GlcNAc beta 1-3Gal beta 1-4Glc, have been described recently. The terminal trisaccharide of this determinant, fucosyllactosamine, is present on glycolipids and glycoproteins and on the surface of granulocytes, monocytes, and other cells. To study the structural and genetic diversity of these antibodies, syngeneic anti-idiotypic monoclonal antibodies were produced in BALB/c mice against PMN 6, a monoclonal antibody directed against this sequence. Anti-idiotypic antibodies 6B1 and 6C4 reacted with 50% of a panel of 20 anti-LNF III monoclonal antibodies, whereas 6A3 reacted strongly only with PMN 6. This indicates that the determinants recognized by 6C4 and 6B1 represent major cross-reactive idiotopes of this family of antibodies. The binding of idiotypic antibodies to a glycolipid bearing this antigenic determinant was completely inhibited by the three anti-idiotypic ...

0073] In such embodiments, the AIC antibody typically is not recognized by the Protein A, Protein G, or Protein A/G. For example, the AIC antibody can be an antibody fragment or variant that lacks the Protein A, Protein G, or Protein A/G binding site on the Fc region of the AIC. The AIC can also be of an isotype that is not recognized (specifically bound) by Protein A, Protein G, or Protein A/G, or the AIC can be an antibody derived from a species that is not recognized by Protein A, Protein G, or Protein A/G. For example, Protein A, Protein G, and Protein A/G do not show significant binding to chicken antibodies, so the AIC antibody for an immune complex comprising a primary antibody and Protein A, Protein G, or Protein A/G can be derived from a chicken. Protein A does not show significant binding to antibodies from horse, human IgG3, human IgD, mouse IgG1, rat or sheep. Thus, where the immune complex comprises a primary antibody and Protein A, the AIC antibody can be derived from an antibody ...

We have identified a set of natural IgM antibodies in human serum that are reactive with protamines, a class of low molecular weight basic nucleoproteins that are synthesized de novo in the postpubertal testis and are unique to sperm. Those antibodies were detected by ELISA in significant titer in all of 100 sera of normal adult males and females and in 26 of 28 sera of normal pediatrics aged 7 d to 2 yr. Commonality between the protamine-reactive IgM antibodies of pediatric and adult sera was established by the demonstration of similarity in antigen recognition and reaction kinetics. Therefore, the role of protamines as either immunogenic stimulus or antigenic target of that set of natural antibodies is not likely. The antigenic site recognized by the protein-reactive serum IgM antibodies was characterized by comparison with the pattern of antigen recognition by a monoclonal antibody to human sperm protamines (HPmAb). By the use of synthetic peptides simulating the amino acid sequences of ...

The Anti-Histone H3 Mouse Monoclonal Antibody (2D10) is otherwise known as Hist1h3a antibody getting its name from Histone H3, one of the five major histone proteins. Histone H3 is involved in the structuring of chromatin in eukaryotic cells and a major component of nucleosome. Nucleosome wrap and compact DNA limit DNA accessibility to the cellular machineries requiring DNA as a template. Therefore, histones play a pivotal role in the transcription, regulation, DNA replication, repair and chromosomal stability.. The Histone H3 antibody has a human, mouse, rat and yeast reactivity with recombinant protein immunogen and the mouse as host.

The product is available in liquid solution and has been affinity-purified from mouse ...

Monoclonal antibodies (MAbs) are made by identical immune cells and target one particular epitope by monovalent or monospecific affinity. The high affinity and selective binding of MAbs to epitopes in target antigens makes them highly potent tools for use in biochemistry, molecular biology and medicine. The first working method described for the isolation of monoclonal antibodies was hybridoma technology, based on forming hybrid cell lines (hybridomas) by fusing an antibody-producing B-cell with a myeloma cell [1]. The antibodies produced by a particular hybridoma clone share the same specificity. Thus, individual clones can be screened for the production of an antibody with the desired affinity. However, hybridoma technology has shortcomings: it takes a relatively long time (on the order of months) and has not been widely applied to organisms other than mice. Moreover, antibody sequence information is unavailable by this method. Thus, when a hybridoma-screened antibody is selected for further ...

Antibodies named TcCRA Trypanosoma cruzi Combination Reactive Antibodies were detected in 47% of bloodstream donors from France population unexposed towards the parasite. in 4 out of 24 patients who received hematopoietic stem cells from positive donors. Here, we are discussing possible scenarios to explain TcCRA-immune status in recipient after transplantation. Introduction In the course of biomarker evaluation of a neglected disease (Chagas disease), we made a remarkable observation of a highly prevalent antibody specificity in unexposed European serum samples. These specific antibodies were named Cross Reactive Antibodies (TcCRA) to stress out the fact that they were induced by another antigen than the one from al 2013 [1]. All the collected samples were tested in duplicate at least one time, if necessary twice, for validation. For some patients we tested serum for anti-measles, anti-mumps and anti-CMV IgGs. Those assessments were performed by using the corresponding Enzygnost kit from ...

10-plate (plates NOT included). Monoclonal antibody to marmoset interleukin 13 (IL-13); Mouse IgG|sub|1. Biotinylated polyclonal antibody to marmoset interleukin 13 (IL-13); Rabbit IgG. 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

Background: There are two subclasses of human IgA (IgA1 and IgA2) that differ in antigenic properties and in chemical composition. The constant domains of α1 and α2 heavy chains have |95% sequence homology though major structural differences exist in the hinge region. Quantitation of IgA subclass levels depends on the availability of monoclonal antibodies (MAbs) specific for conserved conformational or linear epitopes restricted to each subclass. Objective: To produce, select and characterize monoclonal antibodies specific for human IgA2. Methods: Splenocytes from BALB/C mice immunized with a human IgA2 myeloma protein were fused with SP2/0 myeloma cells. Fused cells were grown in hypoxanthine, aminopterine and thymidine (HAT) selective medium and cloned by limiting dilution assay. Antibody (Ab) secreting cells were screened by enzyme-linked immunosorbent assay (ELISA) and the specificity of secreted MAbs was further analyzed, using a panel of purified myeloma proteins and some animal sera by ELISA

The immune system makes an abundance of proteins called antibodies. Antibodies are made by white blood cells (B cells). The antibodies recognize and combat infectious organisms (germs) in the body. Antibodies develop in our immune system to help the body fight infectious organisms. When an antibody recognizes the foreign proteins of an infectious organism, it recruits other proteins and cells to fight off the infection. This cascade of attack is called inflammation.. Sometimes these antibodies make a mistake, identifying normal, naturally-occurring proteins in our bodies as being foreign and dangerous. When these antibodies make incorrect calls, identifying a naturally-occurring protein (or self protein) as foreign, they are called autoantibodies. Autoantibodies start the cascade of inflammation, causing the body to attack itself. The antibodies that target normal proteins within the nucleus of a cell are called antinuclear antibodies (ANA). Most of us have autoantibodies, but typically in ...

Antibodies are known to be a primary correlate of protection in almost all current vaccines, and thus evaluating the antibody response is of critical importance in attempting to predict the efficacy of novel vaccine candidates. Historically antibody responses have generally been detected by measuring the titer (amount of antibody present against a specific antigen) using measurements such as an ELISA or aggluttination assay. In this simple case a high enough level of antibody against the vaccine antigen is sufficient to predict protection. However antibody titer only evaluates one half of the function of antibody, which is dependent on both the variable region (Fv) to bind the antigen target, and the constant region (Fc) to elicit an effector response from other arms of the immune system. In the case of some diseases for which an effective vaccine has so far proven elusive, such as HIV, effector function has been shown to be an important driver of viral control in infected patients, and of ...

One-third of breast cancers display amplifications of the ERBB2 gene encoding the HER2 kinase receptor. Trastuzumab, a humanized antibody directed against an epitope on subdomain IV of the extracellular domain of HER2 is used for therapy of HER2-overexpressing mammary tumors. However, many tumors are either natively resistant or acquire resistance against Trastuzumab. Antibodies directed to different epitopes on the extracellular domain of HER2 are promising candidates for replacement or combinatorial therapy. For example, Pertuzumab that binds to subdomain II of HER2 extracellular domain and inhibits receptor dimerization is under clinical trial. Alternative antibodies directed to novel HER2 epitopes may serve as additional tools for breast cancer therapy. Our aim was to generate novel anti-HER2 monoclonal antibodies inhibiting the growth of breast cancer cells, either alone or in combination with tumor necrosis factor-α (TNF-α). Mice were immunized against SK-BR-3 cells and recombinant HER2

Antibodies can rapidly evolve in specific response to antigens. Affinity maturation drives this evolution through cycles of mutation and selection leading to enhanced antibody specificity and affinity. Elucidating the biophysical mechanisms that underlie affinity maturation is fundamental to understanding B-cell immunity. An emergent hypothesis is that affinity maturation reduces the conformational flexibility of the antibodys antigen-binding paratope to minimize entropic losses incurred upon binding. In recent years, computational and experimental approaches have tested this hypothesis on a small number of antibodies, often observing a decrease in the flexibility of the Complementarity Determining Region (CDR) loops that typically comprise the paratope and in particular the CDR-H3 loop, which contributes a plurality of antigen contacts. However, there were a few exceptions, and previous studies were limited to a small handful of cases. Here, we determined the structural flexibility of the CDR-H3 loop

Anti-glucagon antibodies have shown some efficacy in animal models (Brand et al., 1994, 1996; Sørensen et al., 2006a); however, daily injections of high doses of antibodies were required (Sørensen et al., 2006). The lack of long-term efficacy of the antibody on blood glucose lowering is probably due to a compensatory mechanism involving oversecretion of endogenous glucagon in response to the reduction of glucagon receptor signaling. Increases in circulating glucagon levels have been reported with all modalities blocking the glucagon signaling pathway, which presents technical challenges for both small-molecule GCGR inhibitors and glucagon-neutralizing mAb approaches.. Despite rising glucagon levels, treatment with neutralizing hGCGR mAbs maintained glucose-lowering efficacy. These anti-GCGR mAbs have several desirable attributes as potential therapeutic agents compared with previously pursued approaches. First, mAb B showed a higher affinity than glucagon to the GCGR (Kd = 36 pM versus Kd = ...

Following exposure to HIV and HCV, there is a window period where a person is infected with the virus but does not produce antibodies at a high enough level so they can be detected by antibody detection test methods. During this time, the person is capable of unknowingly transmitting the virus to others. SMARTstim (SMARTube)is a blood sample additive which pre-treats blood, stimulating antibody production in vitro so as to bring it to detectable levels using ELISA (or any other antibody test method). Accelerated antibody production allows antibody detection in specimens that would otherwise be below the detectable limit of antibody test kits. Plasma samples from blood pretreated with SMARTstim are referred to as SMARTplasma.. A total of 1,600 blood samples will be collected and tested using an ELISA for HIV and HCV using FDA-approved test kits. The populations include:. ...

The aim of this study was to look for the presence of IgG, IgM, and IgA antibodies against two widely consumed foods, wheat and milk, in a relatively large number of specimens. As wheat, milk, and their antigens have been found to be involved in neuroimmune disorders, we measured the co-occurrence of their antibodies against various neural antigens. We assessed the reactivity of sera from 400 donors to wheat and milk proteins, GAD-65, cerebellar, MBP, and MOG. Statistical analysis showed significant clustering when certain wheat and milk protein antibodies were cross-referenced with neural antibodies. Approximately half of the sera with antibody elevation against gliadin reacted significantly with GAD-65 and cerebellar peptides; about half of the sera with elevated antibodies against α + β-casein and milk butyrophilin also showed antibody elevation against MBP and MOG. Inhibition studies showed that only two out of four of the samples with elevated cerebellar or MOG antibodies could be inhibited by

The typical method for producing these antibodies is to first induce their production in a model organism, such as a mouse, then extract cells from the mouses spleen, fuse them with a myeloma (a benign cancer cell that divides rapidly) and then use this hybrid cell (known as a hybridoma) to produce many copies of the antibody. Following this the antibodies must be carefully purified before they can be used.. This is a complicated process and fraught with difficulties, getting mice to make the right antibodies and producing the hybridoma is difficult enough for a start. A better approach is to produce recombinant antibodies by inserting DNA encoding them into model cells such as E-coli or yeast, which are much easier to handle. A big advantage here is that it is also possible to make human antibodies, critical for any clinical work. However this synthetic approach is still tough as many recombinant antibodies are not stable enough to survive purification.. This is where the sharks come in. ...

Maintain unopened vial at -70°C for up to 6 months. Avoid repeated freeze/thaw cycles. PREPARATION AND USE: To reconstitute the antibody, centrifuge the antibody vial at moderate speed (5,000 rpm) for 5 minutes to pellet the precipitated antibody product. Carefully remove the ammonium sulfate/PBS buffer solution and discard. It is not necessary to remove all of the ammonium sulfate/PBS solution: 10 µL of residual ammonium sulfate solution will not affect the resuspension of the antibody. Do not let the protein pellet dry, as severe loss of antibody reactivity can occur. Resuspend the antibody pellet in a suitable biological buffer such as PBS or TBS (pH 7.3-7.5) to a final concentration of 1.0 mg/mL. For example, to achieve a 1.0 mg/mL concentration with 50 µg of precipitated antibody, the amount of buffer needed would be 50 µL. Carefully add the liquid buffer to the pellet. DO NOT VORTEX. Mix by gentle stirring with a wide pipet tip or gentle finger-tapping. Let the precipitated antibody ...

Neutralizing is not a general concept; its context-dependent. Most often (in virology anyway) it means that the antibodies, by themselves in a tissue culture plate, can prevent infection of the cells by the virus. Many antibodies that are non-neutralizing in tissue culture are probably protective in the animal, in the context of complement and phagocytic cells and so on. That said, theres no reason why antibodies should be protective, let alone neutralizing. Antibodies dont arise in a guided manner with foreknowledge; antibody development is driven by physical interactions between the antibody and its binding partner. If they happen to arise to something irrelevant -- an internal protein of a virus, or a pollen grain, perhaps -- then they can still be driven through priming and development and maturation and still be functionally useless, or even harmful. On top of that, of course it would be beneficial for pathogens to be resistant to antibodies, and at least a few have evolved this ...

Monoclonal antibodies development has been limited for a long time to only two species : mice and rats. However, the immune systems of mice and rats are not the most suitable in terms of humoral response to certain antigens, such as human antigens like glucagon. Indeed, the protein sequence of glucagon is the same in mice, rats and human (fig. 1). Small not immunogenic antigens, such as antibiotics or toxins, generally failed to trigger an immune response in such species. This is why some companies have developed fusion cell lines to generate monoclonal antibodies in rabbit (Abcam-Epitomics) or in sheep (Bioventix). However, these two tools are not totally satisfactory whether in terms of cost, stability or productivity. SynAbs has therefore opted to develop its own myeloma cell line to manufacture guinea pig monoclonal antibodies and offer more efficient investigation tools for researchers. ...
