Goat Human IgD (Fc specific), conjugated with Biotin Antibody

Biotin-conjugated IgG fraction of polyclonal goat antiserum to human IgD, Fc specific. In immunocytochemical and immunohistochemical staining for the detection of IgD at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates, and to demonstrate circulating antibodies in serodiagnostic microbiology. In non-isotopic assay methodology (e.g. ELISA) to identify and measure IgD in human serum or other body fluid. As a second step an avidin or streptavidin conjugate of the user's choice has to be used. 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 1:1,000 and 1:10,000.
