Sheep IgM (Fc specific) Rabbit Polyclonal Antibody

Specifications

Product Data
Product Name	Sheep IgM (Fc specific) Rabbit Polyclonal Antibody
Applications	ELISA, IF, WB
Recommend Dilution	ELISA. Dot blot. Immunoblotting. Indirect Immunofluorescence. Can be used as unlabelled primary or secondary reagent for indirect detection of IgM at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates; to prepare conjugates of the user’s own choice; to prepare an insoluble immunoaffinity adsorbent or a solid phase antibody reagent by coupling to an artificial carrier and as catching antibody in nonisotopic methodology and solid phase immunochemistry. When applied in any cytochemical or histochemical staining procedure or solid phase coupling technique, the optimum concentration of the IgG preparation should be established by titration before being used. Recommended Working Dilutions: Histochemistry Use: 1/50-1/250. ELISA and comparable non-precipitating antibody-binding assays: 1/500-1/5,000. Precipitin titre: 1/64 when tested against pooled normal sheep serum in agar-block immunodiffusion titration.
Reactivity	Sheep
Host	Rabbit
Immunogen	Purified normal IgM isolated from pooled sheep serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Formulation	PBS, pH 7.2 State: Azide Free State: Lyophilized purified hyperimmune IgG fraction Stabilizer: None Preservative: None, as it may interfere with the antibody activity.
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	Unconjugated
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 crossreacting 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.
