Anti-Human Immunoglobulin M (IgM) Antibody

This unconjugated mouse monoclonal antibody specifically recognizes the human immunoglobulin M heavy chain, supporting characterization of B cell-mediated immunity in research settings. Supplied by Antibodies.com as 1 mg of purified antibody in a vial, it is commonly applied in immunohistochemistry, western blot, and flow cytometry workflows targeting lymphoid tissue, peripheral blood mononuclear cell populations, and isolated B lymphocyte preparations. The unconjugated format allows flexibility for downstream labeling with fluorophores, biotin, or enzymes depending on the experimental design. Researchers studying primary and secondary antibody responses, B cell development in bone marrow and germinal centers, or screening for early humoral responses benefit from IgM-specific detection in both fixed and live cell preparations. The product is suitable for ELISA plate-based capture, immunofluorescence microscopy, and immunoprecipitation protocols that require antibody-specific reactivity against human immunoglobulin isotypes. Each lot is produced from mouse hybridoma cells and purified under conditions that preserve native epitope recognition. Aliquoting upon receipt helps preserve binding activity across repeated freeze-thaw cycles.
