Additional information on a new human isoprecipitin system, directed against Australia antigen, has been given. The antibody defining this system is an IgG(7S) gamma globulin. Staining and ultracentrifugation suggest that Australia antigen contains small amounts of lipid, but is not identical with typical low or high density lipoprotein.
