IgA (Fc specific) polyclonal, anti-rat

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 rat 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 rat serum or other body fluids or to determine its concentration. To prepare an immunoadsorbent for the purification of rat IgA from serum or plasma. This antiserum is not intended for use in non-precipitating antibody-binding or other highly sensitive assays. For such use labelled and unlabelled cytochemical and immunoassay grade reagents meeting the necessary additional specificity and performance requirements are available.

Isotype: Rabbit Polyclonal

Source: Highly purified pools of monoclonal IgA isolated from rat 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: rat

Cross Reactivity:
The antiserum does not cross-react with any other component of the Rat immunoglobulin system. 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.
