Studies on the retention of passively transferred antibodies in man. II. Antibody activity in the blood after intravenous or intramuscular administration of anti-HBs human immunoglobulin.
Catabolism of intravenously or intramuscularly administered human immunoglobulin in man was studied by the administration of HBs antibodies at a high titer and analysis with a highly sensitive radioimmunoassay technique. The half-life in the blood of the antibodies in the aggregate-reduced antibody preparation administered intravenously was found to be 17.7 days and of those in the antibody preparation administered intramuscularly to be 23.8 days.
