Human IgE (Fc specific) Goat Polyclonal Antibody

Specifications

Product Data
Product Name	Human IgE (Fc specific) Goat Polyclonal Antibody
Applications	ELISA, ID, IF, IP, WB
Recommend Dilution	Can be used as unlabelled secondary antibody for Indirect detection of IgE in Human cell, tissue substrates and body fluids in immunofluorescence and immunoenzyme assay methods; for the production of immunoconjugates with a selected marker; to prepare insoluble immunoaffinity adsorbents by coupling to an artificial carrier; as catching or detecting antibody reagent in non-isotopic assay methodology (e.g. ELISA) to identify and measure IgE in human serum or other body fluid. When applied in any immunocytochemical or histochemical staining procedure or solid phase coupling technique, the optimum concentration of the IgG preparation should be established. Recommended Working Dilutions: Histochemical and Cytochemical Use: 1/100-1/250. ELISA and comparable non-precipitating antibody-binding assays: 1/500-1/5,000. Performance testing: Isotype specificity and quantitative specific recognition ability are further evaluated at the high level of sensitivity by direct singe and simultaneous double staining of different types of human cells, using counterstaining with reference conjugates with a different marker. The immunoconjugate is further tested in ELISA-type assays.
Reactivity	Human
Host	Goat
Immunogen	Purified homogenous IgE isolated from Human serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Formulation	PBS, pH 7.2 without preservatives. State: Azide Free State: Lyphilized purified hyperimmune IgG fraction
Concentration	lot specific
Purification	Salt Precipitation and DEAE-Chromatography.
Conjugation	Unconjugated
Storage Condition	Prior to reconstitution store at 2-8°C. Following reconstitution store undiluted at 2-8°C for one month or (in aliquots) at -20°C for longer. Avoid repeated freezing and thawing.
Note	Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required to eliminate antibody activity reacting with other components of the immunoglobulin system and to any other serum protein. Special attention is given to the elimination of antibodies to the common Fab portion of immunoglobulins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.
