Sheep IgM (Fc specific) Rabbit Polyclonal Antibody

Specifications

Product Data
Product Name	Sheep IgM (Fc specific) Rabbit Polyclonal Antibody
Applications	ELISA, IF, IHC, WB
Recommend Dilution	ELISA. Dot blot. Immunoblotting. Immunocytochemistry. Immunohistochemistry Paraffin Sections. Can be used in immunocytochemical and immunohistochemical staining for the detection of IgM at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates; to demonstrate circulating IgM antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen using an reference antibody of sheep origin known to be of the IgM isotype in the middle layer of the indirect test procedure; in non-isotopic assay methodology (e.g. ELISA) to measure IgM in sheep 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: Histochemistry and Cytochemical Use: 1/50-1/250. ELISA and comparable non-precipitating antibody-binding assays: 1/500-1/4,000.
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 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 ~4.6
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	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: Not required
