Abstract
MOUSE leukaemia viruses have not induced overt cytopathic effects in tissue cultures and so the complement fixation technique has been used to detect virus antigens in tissue cultures1. The technique involved sera of rats which were carrying transplanted tumours originally induced by leukaemogenic virus, and extracts of rat tumours. Germ-free and normal rats developed lesions of myelogenous leukaemia after repeated intraperitoneal administrations of sterile 7,12-dimethylbenz(a)anthracene (DMBA) in fat2,3. Viral flora could not be detected in their tissues by electron microscopy, nor by other extensive examinations4. This communication describes the use of the complement fixation technique in a search for disease-related antigens in rats with DMBA-induced leukaemia.
