[Studies on the immunologic specificity of the macrophage-electrophoresis mobility test in mice with syngeneic and allogeneic transplants of mammary carcinoma].

The study was performed to answer the question as to whether the macrophage electrophoretic mobility test (MEM-test) is suitable to detect allogeneic and syngeneic lymphocyte sensitization in the murine mammary tumour host system. Lymph node cells of both CBAf and XVII/Bln mice injected with allogeneic or syngeneic mammary tumour cells reacted specifically to hypertonic KCl extracts from allogeneic or syngeneic mammary tumours. Lymph node cells of nontreated control mice did not react at all. The MEM results reflect lymphocyte sensitizations which are specific with respect to the claim of transplantation and tumour immunology in the system employed.
