Sheep IgG (Fc specific) Rabbit Polyclonal Antibody

Specifications

Product Data
Product Name	Sheep IgG (Fc specific) Rabbit Polyclonal Antibody
Applications	ELISA, IF, IHC
Recommend Dilution	ELISA. Immunocytochemistry. (In)direct Immunofluorescence. Immunohistochemistry on Frozen Sections. Can be used In direct staining of cytoplasmic IgG in fixed sheep cells and tissue substrates; to identify circulating IgG antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen or immune complex using a reference antibody of sheep in the middle layer of the test procedure. 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: 1/20-1/80.
Reactivity	Sheep
Host	Rabbit
Immunogen	Purified normal IgG isolated from pooled sheep serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Formulation	PBS, pH 7.2 Label: FITC State: Lyophilized purified hyperimmune IgG fraction Stabilizer: None Preservative: None, as it may interfere with the antibody activity. Label: Fluorescein isothiocyanate isomer 1 Absorption emission: 492 nm / 515 nm Molar radio: Fluorochrome/IgG ~1.8
Concentration	10.0 mg/ml
Purification	Hyperimmune antisera with strong activity are selected for fractionation by saltprecipitation and purification of the IgG fraction by DEAE-chromatography.
Conjugation	FITC
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.
