General description

Immunoglobulin M (IgM) is the major class of surface immunoglobulins on lymphocyte membranes. IgM is suggested to act as the first line of defense during microbial infections. IgM has a pentameric structure, in which monomers are linking 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 and is involved in B cell maturation and complement activation. Anti-Human IgM (m-chain specific) antibody, Mouse monoclonal specifically recognizes m chain of Human IgM. The antibody shows no cross-reactivity with human IgG, Fab, Fc, k, l, and g chains.


Purified human IgM


The antibody is recommended to use in various immunological techniques, including ELISA and Immunoblot.
