IgE (Fc specific) polyclonal HRP, anti-rat

Quantity: 200 µl

Background:
The reactivity of the antiserum is directed to the Fc subunit of the IgE molecule which expresses strict isotypic (class) specificity as tested against rat serum and a panel of purified homogenous immunoglobulins. In enzyme-immunocytochemical and immunohistochemical staining for the detection of IgE at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates; to demonstrate circulating IgE antibodies in rat serum or other body fluids; in non-isotopic assay methodology (e.g. ELISA) to identify and measure IgE in rat serum or other body fluids.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 1:50 and 1:250; in ELISA and comparable non-precipitating antibody-binding assays vary widely, but may be between 1:1,000 and 1:5,000 depending on the method used.

Isotype: Goat Polyclonal

Source: Purified homogenous IgE isolated from rat serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

Form: Peroxidase-coupled purified hyperimmune goat IgG, in phosphate buffered saline (PBS, pH 7.2).

Specificity:
Horseradish peroxidase-conjugated IgG fraction of polyclonal Goat anti-Serum to Rat IgE, Fc specific.

Reactivity: rat

Cross Reactivity:
Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail.

Applications: ELISA, Immunocytochemistry, Immunohistochemistry (paraffin), Dot blot, Immunoblotting

Storage: Store at 4C, or in small aliquots at -20C.
