Applications	ID, IF, IHC, IP, WB
Recommended Dilution	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 mouse serum or other body fluids; in non-isotopic assay methodology (e.g. ELISA) to identify and measure IgE in mouse 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. Recommended Working Dilutions: Histochemical and Cytochemical: 1/100-1/500. ELISA and comparable non-precipitating antibody-binding assays: 1/1000-1/5000. depending on the method used.
Reactivities	Mouse
Host	Goat
Isotype	IgG
Clonality	Polyclonal
Immunogen	Purified homogenous IgE isolated from pooled Mouse serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Specificity	The reactivity of the antiserum is directed to the Fc subunit of the IgE molecule which expresses strict isotypic (class) specificity as tested against mouse serum and a panel of purified homogenous immunoglobulins. 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.
Formulation	PBS, pH 7.2 without preservatives and foreign proteins Label: HRP State: Lyophilized purified IgG fraction Label: Horseradish Peroxidase.  Enzyme marker: Horseradish peroxidase enriched for isoenzyme C (RZ=3.2).  Conjugation procedure: Conjugation is carried out using a proprietary modification of the periodate technique for the binding to peroxidase, followed by several purification steps. After each step activity and specificity are tested in a variety of techniques. The conjugate is lyophilized to assure stability and long shelf life Molar radio: Peroxidase/IgG: ~1.7
Reconstitution Method	Restore by adding 1.0 ml sterile distilled water
Purification	Immunoaffinity Chromatography
Conjugation	HRP
Storage	Store lyophilized at 2-8°C for 6 months or at -20°C long term. After reconstitution store the antibody undiluted at 2-8°C for one month  or (in aliquots) at -20°C long term. Avoid repeated freezing and thawing.
Note	Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required to eliminate antibodies cross-reacting with other components of the immunoglobulin system or reacting with other serum proteins. Special attention is given to the removal of antibodies to common Ig/Fab. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.um
