Mouse IgG anti-Human IgM (µ) (NI 179)-unconj., MinX none

The reactivity of the antiserum is restricted to an isotype specific determinant of the IgM molecule as tested in indirect binding enzyme immunoassay, immunoblotting, immunoprecipitation and indirect immunoperoxidase staining of cytoplasmic Ig. To identify the presence of IgM in human serum, other body fluids, cell and tissue substrates and to determine its concentration in techniques as ELISA, indirect immunoperoxidase and indirect immunofluorescence staining of cytoplasmic IgM, and immunoblotting. The optimum working dilution is an assay-related characteristic and should always be determined by titration. For histochemical use optimum dilutions are mostly from 1:50 to 1:200, in ELISA from 1:500 upwards, in Western blotting from 1:1,000 upwards. These data should be interpreted as general recommendations only.

Delipidated, heat inactivated lyophilized stable ascites No preservative added, as it may interfere with the antibody activity. No foreign protein added. IgG concentration is 1.0 mg/ml. No foreign proteins added. Reconstitute the lyophilized product by adding 0.5 ml sterile distilled water.
