A highly selective hemagglutinin inhibitor in serums from adult female chickens appears to be activated during extraction of the serum with acetone for removal of the usual lipid inhibitors. The acetone-insoluble inhibitor may be removed by filtration of the serum through Seitz pads. The precursor of the inhibitor in raw serum can be precipitated by two methods of removing euglobulins from solution.
