Abstract
IN recent years, immunochemical investigations on deoxyribonucleic acid (DNA) have suggested the presence of a specific anti-DNA antibody in sensitized animals and also in patient sera of systemic lupus erythematosus. However, the sensitization of an animal has not always met success, and most of the published results about experimental animals are still open to discussion1. It is needed at present to elucidate the fate of the externally introduced DNA. In this communication, tritiated DNA was used as a tracer.
