Goat Human IgG IgA IgM (heavy and light chains), conjugated with Horseradish peroxidase Antibody

Horseradish peroxidase-conjugated IgG fraction of polyclonal goat antiserum to human IgG, IgA and IgM, heavy and light chains. In enzyme-immunocytochemical and immunohistochemical staining for the detection of cytoplasmic Ig at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates, and to demonstrate circulating antibodies in serodiagnostic microbiology and autoimmune diseases. This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labelled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal. Working dilutions for histochemical and cytochemical use are usually between 1:100 and 1:250; in ELISA and comparable non-precipitating antibody-binding assays between 1:1,500 and 1:15,000.
