Rabbit IgM (Fc specific) Goat Polyclonal Antibody

Specifications

Product Data
Product Name	Rabbit IgM (Fc specific) Goat Polyclonal Antibody
Applications	ELISA, ID, IF, IHC, IP, WB
Recommend Dilution	Can be used in Immunocytochemical and Immunohistochemical use 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 goat 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 rabbit 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: 1/100 - 1/250. ELISA and comparable non-precipitating antibody-binding assays: 1/1000 - 1/10000.
Reactivity	Rabbit
Host	Goat
Immunogen	Purified normal IgM isolated from pooled rabbit serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Formulation	PBS, pH 7.2 without preservatives and foreign proteins Label: Biotin State: Lyophilized IgG fraction Molar radio: Biotin/IgG: ~4.9
Concentration	10.0 mg/ml
Purification	Ammonium Sulphate Precipitation and Ion Exchange Chromatography
Conjugation	Biotin
Storage Condition	Prior to and following reconstitution store the antibody at 2-8°C for one month or at -20°C for longer. 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.
