Abstract
- In the present paper we demonstrate that there is an antigenic determinant common to two different types of human teukaemia-associated antigens. i.e. human thymus Ieukaemia-associated (HTL) antigens and common acute lymphoblastic leukuemia (cALL) antigen. In addition, there are distinct antigenic determinants which are unique to the HTL antigens or to the cALL antigen. The new, common antigenic determinant will be useful as a new differentiation marker of human haematopoietic cells as well as a new Ieukaemia-associated marker. In the present study. we used several different anti-human leukaemia antisera which include those prepared by immunizing rabbits (Nos. 7549 and 7550) with purified HTL antigens. The antisera 7549 and 7550, without any absorption1 showed strong specificity as well as strong antibody activity toward Ieukaemia cells. These are the first anti-human leukaemia antisera, except for the monoclonas hybridoma antibodies, that show good specificity for leukaemia cells without prior absorption. [ABSTRACT FROM AUTHOR]
