Guinea Pig IgG (Fc specific) Sheep Polyclonal Antibody

Specifications

Product Data
Product Name	Guinea Pig IgG (Fc specific) Sheep Polyclonal Antibody
Applications	ELISA, IF, IHC, WB
Recommend Dilution	ELISA. Dot blot. Immunoblotting. Immunocytochemistry. Immunohistochemistry on Paraffin Sections. In immunocytochemical and immunohistochemical staining of IgG at the cellular and subcellular level of appropriately treated cell and tissue substrates; to demonstrate circulating IgG antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen using a reference antibody of guinea pig origin known to be of the IgG isotype in the middle layer of the indirect test procedure; in non-isotopic assay methodology (e.g. ELISA) to measure IgG in guinea pig serum or other body fluids. 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. Recommended Working Dilutions: Histochemical and Cytochemical Use: 1/100-1/250. ELISA and comparable non-precipitating antibody-binding assays: 1/1,000-1/5,000.
Reactivity	Guinea Pig
Host	Sheep
Immunogen	Purified normal IgG isolated from pooled guinea pig serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Formulation	PBS, pH 7.2 Label: Biotin State: Lyophilized purified hyperimmune IgG fraction Stabilizer: None Preservative: None, as it may interfere with the antibody activity Label: N-Hydroxysuccinimidobiotin Molar radio: Biotin/IgG protein ~4.5
Concentration	10.0 mg/ml
Purification	Hyperimmune antisera with strong precipitating activity are selected for fractionation by salt-precipitation and purification of the IgG fraction by DEAE-chromatography.
Conjugation	Biotin
Storage Condition	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. Conjugation procedure: Conjugation is carried out using a proprietary technique for the binding to biotin, 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. No foreign protein has been added.
