• Host: Sheep
• Conjugate: Unconjugated
• Concentration: LYOPH

Sheep anti-Human IgA/Secretory Component Secondary Antibody Summary

• Description: The lyophilized antiserum is shipped at ambient temperature and may be stored at 4C; prolonged storage at or below -20C. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at 4C, not refrozen, and preferably used the same day.
• Immunogen: Highly purified IgA/Secretory Component isolated from pooled human milk. 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 IgA molecule and to surface and hidden determinants of the secretory component as tested in immunoelectrophoresis and radial immunodiffusion. In immunoelectrophoresis using various antiserum concentrations against normal human milk two precipitin lines may be obtained, one representing IgA and the other the free secretory component. Against normal human serum only IgA is precipitated. No precipitation reaction is obtained with purified IgG, IgM, and IgG/Fab fragments.
• Clonality: Polyclonal
• Host: Sheep
• Purity: Whole Antiserum

Applications/Dilutions

• Dilutions:
  • Immunoelectrophoresis
• Application Notes: Precipitation assays.

Reactivity Notes

The antiserum does not cross-react with any other component of the Human Ig system. Interspecies 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: Whole antiserum
• Preservative: No Preservative
• Concentration: LYOPH
• Purity: Whole Antiserum
• Reconstitution Instructions: Reconstitute the lyophilized antiserum by adding 1 ml sterile distilled water. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2).
