    Protocol

    Specificity / Sensitivity

    IgM (E9U8J) XP® Rabbit mAb recognizes endogenous levels of total IgM heavy chain protein. This antibody reacts with secreted and membrane bound isoforms of IgM heavy chain protein.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu310 within the constant region of human IgM heavy chain protein.

    Background

    Immunoglobulin M (IgM) is one of the five major human immunoglobulin isotypes and is the first antibody to be secreted by plasmablasts in a humoral immune response after exposure to antigen. Structurally, IgM is the largest immunoglobulin and predominantly exists in pentameric form when secreted (1). Alternative splicing of the IgM heavy chain mRNA can generate an alternative form of the antibody, which facilitates its insertion into the plasma membrane of B cells to function in antigen recognition. IgM is the first Ig isotype to appear on the surface of developing B cells and is a major component of the B cell antigen receptor (BCR) signaling complex, which drives B cell survival and proliferation upon antigen-induced ligation (2,3). Research studies have shown that defects in the assembly of the BCR account for the low levels of surface IgM expression in B-chronic lymphocytic leukemia (4,5).
