Abstract
Summary
(1) By techniques of radioimmunoelectrophoresis and radioimmunodiffusion using radioactive poliovirus, it was shown that the quantity of poliovirus antibodies in a serum and the immunoglobulin class of these antibodies can be determined. (2) By these techniques it was shown that adult human serum contains A Immunoglobulin (IgA) poliovirus antibodies as well as G Immunoglobulin (IgG) polio antibodies. (3) Some sera contain a higher concentration of A Immunoglobulin (IgA) polio antibodies than G Immunoglobulin (IgG) polio antibodies.
