Guinea Pig IgM (Fc specific) sheep polyclonal antibody, Serum

Specifications

Product Data

• Applications: ID, IP
• Recommended Dilution: Immunoprecipitation.
  Can be used in precipitating techniques as immunoelectrophoresis and radial immunodiffusion to identify the presence of IgM in guinea pig serum and other body fluids or to determine its concentration. To prepare an immunoadsorbent for the purification of guinea pig IgM from serum or plasma.
  Directions for Use:
  Immunoelectrophoresis: Use 2 µl or equivalent against 120 µl antiserum.
  Double Radial Immunodiffusion use a rosette arrangement with 10 µl antiserum in a 3 mm diameter centre well and 2 µl serum samples (neat and diluted) in 2 mm diameter peripheral wells.
  Antibody titre: Precipitin titre not less than 1/32 when tested against normal guinea pig serum in agar block titration.
• Reactivities: Guinea Pig
• Host: Sheep
• Clonality: Polyclonal
• Immunogen: Highly purified normal IgM isolated from pooled guinea pig serum.
  Freund’s complete adjuvant is used in the first step of the immunization procedure.
• Specificity: The reactivity of the antiserum is restricted to the Fc part of the IgM molecule. In immunoelectrophoresis and radial immunodiffusion, using various antiserum concentrations against normal guinea pig serum a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified IgM. No precipitation reaction is obtained with purified IgG, IgA, and IgG/Fab fragments.
  Cross-reactivity: The antiserum does not cross-react with any other component of the guinea pig Ig system. 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: State: Serum
  State: Lyophilized (delipidated, heat inactivated) stable whole antiserum without preservatives
• Reconstitution Method: Restore by adding 1 ml of sterile distilled water
• Concentration: Total protein and IgG concentrations in the antiserum are comparable to those of pooled normal sheep serum. No foreign proteins added.
• 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 cross-reacting with other components of the immunoglobulin system or reacting with other serum proteins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.
