Mouse IgG anti-Human IgG (Fc) (NI 335 + NI 343)-unconj., MinX none

The reactivity of the antiserum is restricted to isotype specific determinants on the Fc part of the IgG molecule. It reacts with the 4 subclasses of human IgG, as tested in indirect binding enzyme immunoassay, immunoblotting, immunoprecipitation and indirect immunoperoxidase staining of cytoplasmic Ig. To identify the presence of IgG 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 IgG, 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.

Purified mouse IgG1 kappa lyophilized from a solution in phosphate buffered saline (pH 7.2). No preservative added, as it may interfere with the antibody activity. No foreign protein added. IgG concentration is 0.4 mg/ml. No foreign proteins added.
