    CF® dye goat anti-human IgM (μ chain) is labeled with our bright, fluorescent dyes and is prepared from antibodies purified by human IgM-affinity chromatography. The antibodies react specifically with IgM heavy chains (μ chains) and not with immunoglobulin light chains. To minimize crossreactivity, it has been adsorbed against human IgG prior to conjugation.
