Immunogen
|
Highly purified secretory IgA isolated from pooled goat milk. Freund's complete adjuvant is used in the first step of the immunization procedure.
|
Isotype
|
IgG
|
Specificity
|
The reactivity of the antiserum is restricted to the Fc part of the IgA molecule as tested in immunoelectrophoresis and radial immunodiffusion. In immunoelectrophoresis using various antiserum concentrations against normal goat serum only IgA is precipitated. No precipitation reaction is obtained with purified IgG, IgM, and IgG/Fab fragmentsPrecipitating polyclonal swine antiserum to goat IgA
|
Characteristics
|
Total protein and IgG concentrations in the antiserum are comparable to those of pooled normal swine serum. Antibody titre: Precipitin titre 1:32 when tested against pooled normal goat serum in agar-block immunodiffusion titrati
|
Purification
|
Delipidated, heat inactivated, lyophilized, stable whole antiserum Immunoaffinity adsorbed using insolubilized antigens as required, to eliminate antibodies cross-reacting with other components of the immunoglobulin system or reacting with other serum or milk proteins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.
