Goat Rat IgE (Fc specific), conjugated with Biotin Antibody

• Catalog Number: orb21608
• Category: Antibodies
• Description: Biotin-conjugated IgG fraction of polyclonal goat antiserum to Rat IgE, Fc specific. In immunocytochemical and immunohistochemical staining for the detection of IgE 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 IgE in rat 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 1:500; in ELISA and comparable non-precipitating antibody-binding assays between 1:1,000 and 1:10,000.
• Clonality: Polyclonal
• Species/Host: Goat
• Conjugation: Biotin
• Reactivity: Rat
• Form/Appearance: Biotin-coupled purified hyperimmune goat IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2). No preservative added, as it may interfere with the antibody activity.
• RRID: AB_10735733
• Antibody Type: Secondary Antibody
• Source: Purified homogenous IgE isolated from rat serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
• Storage: The lyophilized conjugate is shipped at ambient temperature and may be stored at +4°C; prolonged storage at or below -20°C. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at +4°C, not refrozen, and preferably used the same day.
• Note: For research use only
• Expiration Date: 12 months from date of receipt.
