IgA (Fc specific) polyclonal, anti-caprine

Quantity: 200 µl

Background:
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 fragments. In precipitating techniques as immunoelectrophoresis and radial immunodiffusion to identify the presence of IgA in goat serum or other body fluids or to determine its concentration. To prepare an immunoadsorbent for the purification of goat IgA from serum or exocrine secretions. Antisera to IgA do not discriminate between serum IgA (monomeric and dimeric) and higher molecular forms as secretory IgA. This antiserum is not intended for use in non-precipitating antibodybinding or other highly sensitive assays. This does not exclude such use if proper controls are include.

Isotype: Swine Polyclonal

Source: Highly purified secretory IgA isolated from pooled goat milk. Freund's complete adjuvant is used in the first step of the immunization procedure.

Form: Delipidated, heat inactivated, in PBS and 0.1% sodium azide.

Reactivity: Caprine

Cross Reactivity:
The antiserum does not cross-react with any other component of the Goat Ig system or any other plasma protein. 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.

Applications: Immunoprecipitation

Storage: Store at 4C, or in small aliquots at -20C.
