Mouse anti Bovine IgG2, clone IL-A73, is a monoclonal antibody specific for bovine IgG2 and does not recognise other bovine immunoglobulin classes.

While normal serum levels of IgG1 are relatively constant in cattle at around 50%, IgG2 levels are highly variable between different strains and races.

Mouse anti Bovine IgG2, clone IL-A73 immunoprecipitates a protein band of approximately 52-59kDa, consistent with the heavy chain of bovine IgG2 (Campbell et al. 1998).
