The reactivity of the antiserum is restricted to determinants on the C H 2 domain of IgA. It reacts with both subclasses of IgA 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). Horseradish peroxidase-conjugated purified monoclonal mouse antibody to human IgA, isotype specific
Attributs du produit
Peroxidase/IgG protein molar ratio (E/P) approximately 1.7. Enzyme marker Horseradish peroxidase enriched for isoenzyme C (RZ=3.2).
Purification
Purified
Immunogène
Highly purified monoclonal IgA isolated from human serum.
To identify the presence of IgA in human serum, other body fluids, cell and tissue substrates and to determine its concentration in techniques as ELISA, immunoperoxidase staining of cytoplasmic IgA, and immunoblotting. As a second step an avidin or streptavidin conjugate of the customer's choice have to be used. 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 1:10 to 1:50, in ELISA from 1:50 upwards, in Western blotting from 1:100 upwards. Working dilutions may vary widely, strongly depending on the test conditions. These data should be interpreted as general recommendations only.
