This entire complex (capture antibody\/analyte\/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. CatchPoint HRP Development Solution containing the Stoplight Red Substrate is added. During incubation, the substrate is catalyzed by HRP generating a fluorescent product. Signal is generated proportionally to the amount of bound analyte and the intensity is measured in a fluorescence plater reader at 530\/570\/590 nm Excitation\/Cutoff\/Emission.\u003cbr\u003e\nImmunoglobulin M, or IgM, is a basic antibody produced by B cells and the largest of the immunoglobulins in the Human circulatory system. IgM typically constitutes about 10% of serum immunoglobulins and is prominent in the early immune responses. IgM (with IgD) is the major immunoglobulin expressed on the surface of B cells. IgM typically forms pentamers which includes the J chain, while in the less common hexameric form the J chain is absent. Although the common pentameric form of IgM contains 10 antigen binding sites, IgM cannot bind 10 antigens simultaneously due to size constraints. Class specific anti-immunoglobulin antibodies are useful for the characterization of malignant B cell proliferations. Most lymphocytic leukemias share either surface or intra cytoplasmic Ig with an isotypic restriction, which suggest the monoclonal nature of the cell population. Most of the chronic lymphocytic leukemias, non Hodgkin lymphomas and Burkitt's lymphoma bear surface IgM, whereas plasmocytes from Waldenström's disease bear intracytoplasmic IgM.\u003cbr\u003e\nREACH authorisation\u003cbr\u003e\nAbcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.\u003cbr\u003e\nIt is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nIgM also known as immunoglobulin M is a type of antibody with a molecular mass of approximately 970 kDa. It is the largest antibody present in the human circulatory system mostly found in plasma and lymphatic tissue. IgM is secreted primarily by B cells as a pentamer with a J chain providing a high avidity for antigens. When bound to an antigen IgM can activate the complement system a part of the immune system that helps clear pathogens from an organism.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nIgM acts as the first line of defense during the initial stages of an immune response. It plays an important part in agglutination and neutralization of pathogens forming a complex that alerts other components of the immune system to take action. IgM exists before class-switching to IgG providing immediate protection. It also plays a role in antibody-dependent cellular cytotoxicity. Although not typically a long-term solution its presence is critical for providing initial protection until more specific antibodies like IgG and IgA are produced.\u003cbr\u003e\nPathways\u003cbr\u003e\nThe immune response that involves IgM begins with the activation of the classical complement pathway. This pathway bridges the innate and adaptive immunity ensuring the communication and coordination of immune responses. The pathway involves C1q protein binding to IgM-antigen complexes. IgM also interacts with antigen-presenting cells facilitating the processing of antigens and interaction with T cells. These interactions connect IgM with other proteins like IgG and IgA influencing various immune response pathways.\u003cbr\u003e\nIgM is associated with conditions such as Waldenström's macroglobulinemia and rheumatoid arthritis. Waldenström's macroglobulinemia involves the overproduction of IgM by clonal B cells leading to symptoms like anemia bleeding and neuropathy. Rheumatoid arthritis shows increased IgM levels as part of the autoimmune response affecting joints. In these diseases the IgM antibody interacts with rheumatoid factor and other immune proteins involved in inflammation demonstrating its significant role in autoimmunity and abnormal immune responses.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46855645724841,"sku":"ab229385","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab229385","provider":"Iright","version":"1.0","type":"link"}
