Goat anti Swine IgG (heavy and light chains)

The reactivity of the antiserum is directed to the Fc and Fab subunits of both subclasses, IgG1 and IgG2. In immunoelectrophoresis against swine serum, a single characteristic precipitin line is usually observed, representing primarily Igg2. The IgG1 may become visible a spur. The antiserum includes a certain degree of reactivity with other immunoglobulins via the common Fab portion. In immunoelectrophoresis against swine serum a single characteristic precipitin line with a spur is usually obtained. It does not react with any non-Ig protein in swine serum, as tested by immunoelectrophoresis and double radial immunodiffusion. In immunoelectrophoresis and double radial immunodiffusion to identify the presence of IgG; as secondary antibody to precipitate the immunoglobulin in normal swine serum; to prepare an immunoadsorbent for the production of Ig-free swine serum, plasma or non-Ig preparations. This antiserum is not intended for use in non-precipitating antibody-binding or other highly sensitive assays. For such uses labelled and unlabelled cytochemical and immunoassay reagents meeting the necessary additional specificity and performance requirements are available.
