Maus IgG anti-Human IgA2 (NI 512,A89-038)-FITC, MinX keine

The reactivity of the antiserum is restricted to an subclass specific determinant on IgA2 molecule as tested in haemagglutination, haemagglutination inhibition, direct binding enzyme immunoassay, competitive inhibition enzyme immunoassay, immunoblotting, immunoprecipitation, latex agglutination assay and histochemistry (Results of an IUIS/WHO collaborative study, Mestecky J. et al. (1996) J. Immunol. Methods 193, 103-148). To identify the presence of IgA2 in human serum, other body fluids, cell and tissue substrates and to determine its concentration in techniques as immunofluorescence staining of cytoplasmic IgA2, and immunoblotting using a peroxidase labelled monoclonal antibody against FITC. The optimum working dilution is an assay-related characteristic. It may vary widely and should always be determined by titration. For histochemical use optimum dilutions are mostly from 1:20 to 1:100, in Western blotting from 1:200 upwards.

Purified monoclonal mouse IgG1 kappa conjugated with FITC, lyophilized from a solution in phosphate buffered saline (pH7.2). No preservative added, as it may interfere with the antibody activity. No foreign protein added. Reconstitute the lyophilized product by adding 0.5 ml sterile distilled water.
