Cell surface antigens of L-1210 leukemia recognized by monoclonal antibodies.
Conventional antisera to L-1210 leukemia were being prepared in our laboratory for nearly a decade and consistently the only specificity detectable was anti Mammary Leukemia antigen (ML). Serological analysis of five monoclonal antibodies obtained following the same immunization schedule showed more diverse pattern of reactivity. Two antigens detected belong to oncofetal category. The third one is differentiation antigen Ly-6 and the nature of two others, expressed on leukemic cells only, remains at present unclear. Thus none of the clones analysed produces antibodies to ML antigen. Our previous analysis of cell surface antigens of L-1210 leukemia with the use of conventional antisera has already been described. This paper presents the results of applying monoclonal antibodies in a comparable studies.
