BD, CYT-IGMAP, IgM-APC SADA4

IgM antibody, clone MHM-88, is designed for flow cytometry use as a direct immunofluorescence reagent in the identification and enumeration of IgM expressing cells. Monomeric IgM is always the first form and isotype of Ig generated by naive B cells. Following its initial activation by antigen, the naive B cell proliferates and differentiates, and its progeny produce the pentameric secreted form of IgM. Thus, it is IgM antibodies that are expressed first in any primary immune response.
