Can be used to identify IgM at the cellular and subcellular level by immunofluorescence staining of appropriately treated cell and tissue substrates, and to demonstrate circulating antibodies in serodiagnostic microbiology and autoimmune diseases, where IgM and IgG antibodies can be expected. 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.
Reactivities Sheep
Host Rabbit
Isotype IgG
Clonality Polyclonal
Immunogen Purified normal IgM isolated from pooled sheep serum.
Freund’s complete adjuvant is used in the first step of the immunization procedure.
Specificity The reactivity of the antiserum is directed to the Fc and Fab subunits of the IgM molecule. It includes a certain degree of reactivity with other immunoglobulins via the common Fab portion. It does not react with any non-Ig protein in sheep serum, as tested by immunoelectrophoresis and double radial immunodiffusion.
Cross-reactivity: Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail.
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 ~1.4
Reconstitution Method Restore with 1 ml sterile distilled water.
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 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.
Conjugation procedure: A proprietary technique for the binding to FITC is used, followed by several purification steps to remove free reactants and protein aggregates. After each step activity and specificity are tested in a variety of techniques. The conjugate is lyophilized to assure stability and long shelf life.
