Grass pollen specific antibody in the plasma of normal dogs

An investigation carried out with healthy beagle dogs showed that their plasmas contained detectable levels of grass pollen specific IgG antibody, as measured by a radiometric assay involving the binding of IgG to radio-iodinated staphylococcal protein A. These samples did not, however, contain detectable homocytotropic-type antibodies specific for grass pollen extract.
