产品说明
一般描述
Monoclonal Anti-Human IgM (mouse IgG2b isotype) is derived from the MB-11 hybridoma, produced by the fusion of mouse myeloma cells and splenocytes from a BALB/c mouse immunized with purified human IgM protein. Immunoglobulin M (IgM) is the major class of surface immunoglobulins on lymphocytes membranes. IgM has a pentameric structure, in which monomers are linked together via disulfide bonds. Surface IgM is expressed on immature and mature B cells, whereas IgM heavy chain is expressed intracellularly in pre-B cells. IgM serves as the antigen receptor of naive B cells.
特异性
Monoclonal Anti-Human IgM (μ-chain) specifically recognizes μ chain of Human IgM. The antibody shows no cross-reactivity with human IgG, Fab, Fc, kappa, lambda and gamma chains.
免疫原
purified human IgM protein
应用
Monoclonal Anti-Human IgM (μ-chain specific)-Peroxidase antibody produced in mouse may suitable for use in enzyme-linked immunosorbent assay (ELISA).
生化/生理作用
IgM is suggested to act as the first line of defense during microbial infections. Secreted IgM (sIgM) is involved in B cell maturation and complement activation. Detection of IgM antibodies in a patient′s serum may indicates a recent infection and IgM in a neonate′s serum may indicate on intrauterine infection (e.g. congenital rubella syndrome). In addition, the development of anti-donor IgM after combined liver-kidney transplantation has been shown to provide a graft- protecting effect. Anti-Human IgM (μ-specific) antibodies can be used in detection of the abnormal concentration of IgM in patient sera and IgM-associated pathologies, such as selective IgM immunodeficiency (SIgMD) and the hyperimmunoglobulin M (hyper-IgM or HIGM) syndromes.
