CAT#: AP21443FC-N

Chicken IgM (Fc specific) goat polyclonal antibody, FITC

Specifications

Product Data

• Applications: ID, IF, IHC
• Recommended Dilution: Can be used in Immunocytochemical and Immunohistochemical staining of IgM at the cellular and subcellular level of appropriately treated cell and tissue substrates; to demonstrate circulating IgM antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen using a reference antibody of chicken origin known to be of the IgM isotype in the middle layer of the indirect 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.
  Recommended working dilutions: 1/10 - 1/40, depending on the method used.
• Reactivities: Chicken
• Host: Goat
• Isotype: IgG
• Clonality: Polyclonal
• Immunogen: Purified IgM isolated from chicken 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 subunit of the IgM molecule, which expresses strict (class) specificity. In immunoelectrophoresis and radial in immunodiffusion using various antiserum concentrations against chicken serum, a single precipitin line has been obtained which shows a reaction of identity with the precipitin lines obtained with the purified IgM used as immunogens. It does not react with IgG, IgG/Fab fragments and IgA or any non-Ig protein in chicken serum, as tested by immunoelectrophoresis and double radial immunodiffusion.
  Cross-reactivity: This immunoconjugate is not species-specific since inter-species cross-reactivity is a normal feature of antisera to immunoglobulins. Cross-reactivity of this antiserum has not been tested in detail.
• Formulation: PBS, pH 7.2 without preservatives and foreign proteins
  Label: FITC
  State: Lyophilized hyperimmune IgG fraction
  Label: Fluorescein Isothiocyanate isomer 1
  Absorption emission: 492 nm / 515 nm
  Molar radio: Fluorescein/IgG ~ 1.7
• Reconstitution Method: Restore by adding 1.0 ml of sterile distilled water
• Concentration: 10,0 mg/ml
• Purification: Ammonium Sulphate Precipitation and Ion Exchange Chromatography
• Conjugation: FITC
• Storage: 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.
