CAT#: AP33084SU-N

Sheep IgM (H+L chain) rabbit polyclonal antibody, Serum

Specifications

Product Data

• Applications: ID, IP
• Recommended Dilution: Immunoprecipitation.
  Can be used in immunoelectrophoresis and double radial immunodiffusion to identify the presence of IgM and IgG antibodies, as secondary antibody to precipitate the immunoglobulin in normal sheep serum, to prepare an immunoadsorbent for the production of Ig-free sheep serum, plasma or non-Ig preparations.
  Recommended Working Dilutions:
  Immunoelectrophoresis: Use 2 µl or equivalent against 120 µl antiserum.
  Double Radial Immunodiffusion (Ouchterlony): 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: 1/64 when tested against pooled normal sheep serum in agar-block immunodiffusion titration.
• Reactivities: Sheep
• Host: Rabbit
• Clonality: Polyclonal
• Immunogen: Highly 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: State: Serum
  State: Delipidated, heat inactivated lyophilized stable whole serum
  Stabilizer: None
  Preservative: None, as it may interfere with the antibody activity.
• Reconstitution Method: Restore with 1 ml sterile distilled water.
• Concentration: Total protein and IgG concentration in the antiserum are comparable to those of pooled rabbit 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: Not required.
