Mouse anti Bovine IgG2, clone K192 4F10, is a monoclonal antibody specific for bovine IgG2 (A1/A1 & A1/A2) and does not recognize other bovine immunoglobulin classes.

Clone K192 4F10 has been shown recognise IgG2 in some, but not all, breeds of sheep.

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