Clone: Polyclonal
Background: The reactivity of the antiserum is restricted to the Fc part of the IgA molecule and the surface and hidden determinants of the secretory component. In immunoelectrophoresis and radial immunodiffusion, using various antiserum concentrations against normal cat milk two precipitin lines may be obtained, one representing IgA and the other the free secretory component. Against normal cat serum only IgA is precipitated. No precipitation reaction is obtained with purified IgG, IgM, and IgG/Fab fragments. In precipitating techniques as immunoelectrophoresis and radial immunodiffusion to identify the presence of IgA in cat milk or other body fluids or to determine its concentration. To prepare an immunoadsorbent for the purification of cat IgA from serum or exocrine secretions. Antisera to IgA or sIgA do not discriminate between serum IgA (monomeric and dimeric) and higher molecular forms such as secretory IgA. This antiserum is not intended for use in non-precipitating antibody-binding or other highly sensitive assays. This does not exclude the use of the antiserum in more sensitive techniques if proper controls are included.
Source: Highly purified secretory IgA isolated from pooled cat milk. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Specificity: Precipitating polyclonal Goat antiSerum to Cat secretory IgA
Formulation: Delipidated, heat inactivated, lyophilized, stable whole antiserum No preservative added. Total protein and IgG concentrations in the antiserum are comparable to those of pooled normal goat serum. No foreign proteins added.
