Mouse anti Pig IgG2, clone K68 Ig2 recognizes porcine IgG2 and shows no cross-reactivity with IgG1, IgA or IgM. IgG2 (IgG2a and IgG2b), along with IgG1, IgG3 and IgG4 comprise the major known subclasses of IgG in swine. Combined, the various subclases of IgG comprise approximately 85% of immunoglobulin in porcine serum.

Studies using clone K68 Ig2 have demonstrated that along with IFNγ, porcine IgG2 levels are significantly elevated in parasite infections by worm species such as Schistosoma japonicum (Tian, F. et. al. 2010). With changes in agricultural practices and the ermergence of new strains of porcine diseases, it has been suggested that new methods of vaccine development should be investigated. Studies have shown that antibodies recognizing porcine immunoglobulins such as clone K68 Ig2 may have potential use in porcine vaccine development studies (Rodríguez-Calvo, T. et. al. 2010).

Clone K68 Ig2 forms part of a range of monoclonal antibodies specific for porcine immunoglobulins and immunoglobulin subclasses that are available from Bio-Rad.
