CAT#: AP31543FC-N

Mouse IgM (Fc specific) goat polyclonal antibody, FITC

Specifications

Product Data

• Applications: ID, IF, IHC, IP
• Recommended Dilution: In direct staining of cytoplasmic IgM in fixed mouse cells and tissue substrates; to identify circulating IgM antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen or immune complex using a reference antibody of mouse 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.
  Working dilutions are usually between 1/20 and 1/80.
• Reactivities: Mouse
• Host: Goat
• Isotype: IgG
• Clonality: Polyclonal
• Immunogen: Purified homogenous IgM isolated from pooled mouse serum. Immunization with intact (19S) and split (7S) IgM. 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 subunit of the IgM molecule. In immunoelectrophoresis and double radial immunodiffusion, using various antiserum concentrations against normal mouse plasma and serum, a single characteristic precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified IgM. No reaction is obtained with purified IgA, IgG and IgG/Fab fragments.
  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 conjugate has not been tested in detail, however this conjugate has been passed over appropriate immunoadsorbents to remove antibodies cross-reacting with human immunoglobulins. This renders it specific for use in test systems containing material of human origin (e.g. human tissue/mouse monoclonal antibody to a human tissue constituent/anti mouse Ig isotype-specific immunoconjugate.
• Formulation: PBS, pH 7.2
  No preservative added, as it may interfere with the antibody activity. No foreign proteins added.
  Label: FITC
  State: Lyophilised hyperimmune Ig fraction
  Label: Fluorescein isothiocyanate isomer 1
  Absorption emission: 492nm / 515nm
  Molar radio: 1,8
• Reconstitution Method: Restore with 1 ml sterile distilled water.
• Concentration: 6,3 mg/ml
• Purification: DEAE-column Chromatography
• Conjugation: FITC
• Storage: Prior to reconstitution store at 2-8°C.
  Following reconstitution store undiluted at 2-8°C for one month
  or (in aliquots) at -20°C for longer.
  Avoid repeated freezing and thawing.
• Note: Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required to eliminate antibodies reacting with other components of the immunoglobulin system or reacting with other serum proteins. The use of insolubilized adsorption antigens prevents the presence of foreign protein or immune complexes in the antiserum.
