IgA (Fc specific) polyclonal, anti-feline

Quantity: 200 µl

Background:
The reactivity of the antiserum is restricted to the Fc part of the IgA molecule. In immunoelectrophoresis and radial immunodiffusion, using various antiserum concentrations against normal cat serum a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified IgA. 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 serum and other body fluids or to determine its concentration. To prepare an immunoadsorbent for the purification of cat IgA from serum or plasma.

Isotype: Rabbit Polyclonal

Source: Highly purified normal IgA isolated from pooled cat serum. 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: Feline

Cross Reactivity:
The antiserum does not cross react with any other component of the Cat 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.

Applications: Immunoprecipitation

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