Reaction of various human normal and leukemic cells and cells of different cell lines with rabbit antisera prepared against membrane fraction of B and T cell lines.
Serological analysis of human membrane antigens have been performed using rabbit xenosera against membrane fraction obtained from different cells (B cell lines: RAJI, RAMOS, DAUDI, UHKT-2: T cell line: MOLT-3, as well as normal pooled lymphocytes). The direct cytotoxicity testing demonstrated that xenogeneic rabbit B lymphoid antisera mediated a significant reaction in the complement-dependent cytotoxicity assay against an antigenic determinant on normal peripheral blood B lymphocytes but not against T lymphocytes and granulocytes. Moreover, these xenoantisera react with antigenic specificities present on the CLL leukocytes, on some AML myeloblasts, on the hairy cells, on majority of ALL and CML blasts, but not on eosinophilic leukocytes and on T lymphocytes from peripheral blood of patients with CLL, ALL, AML, and CML in remission. These xenoantisera react with antigenic specificities present on the cells of cultured lymphoid cell lines of B type, but not on cells of T cell lines.
