Rabbit anti-Sheep IgM (H+L) Secondary Antibody Summary

• Description: The lyophilized conjugate is shipped at ambient temperature and may be stored at 4C; prolonged storage at or below -20C. Prior to use, an aliquot is thawed slowly at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at 4C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the immunoconjugate.
• 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.
• Clonality: Polyclonal
• Host: Rabbit
• Purity: Ion exchange chromatography

Applications/Dilutions

• Dilutions:
  • Dot Blot
  • ELISA
  • Immunoblotting

• Application Notes: Indirect immunofluorescence.

Reactivity Notes

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.

Packaging, Storage & Formulations

• Storage: Store at 4C short term. Aliquot and store at -20C long term. Avoid freeze-thaw cycles.
• Buffer: Lyophilized from PBS (pH 7.2)
