title: [Detection of new antigens, induced by retrovirus D, by a quantitative complement fixation micromethod using radioactive chromium].
abstract: The additional evidence of the existence of antigenic differences between the early virus-induced antigen and structural retrovirus D antigens as well as antigens from human fetus normal tissues was obtained by quantitative complement fixation micromethod using radioactive chromium (51Cr-CFT). In examinations of 13 specimens of cancer tumours and fibroadenomas of the female mammary glands the new antigen was found in 8 cases, including 4 cancer tumours where this antigen could not be detected by the conventional CFT.
