| Abstract: | The hybridization of myeloma cells NP with lymphocytes of mice, immunized with protein isolated from Neisseria meningitidis strain Bc5 in a single injection into the spleen 3 days prior to fusion, made it possible to obtain 25-72% of hybridomas secreting antibodies to meningococcal antigens. The treatment of immune lymphocytes from these mice with the total preparations of nucleic acids, isolated by the phenol-detergent method from mouse myeloma cells NP and NS/0, induced an increase in the proliferative activity of lymphocytes; in some microcultures multilayer cell growth was observed on the bottom of the wells, whereas in the control microcultures such growth was absent. No synthesis of specific antibodies was detected in the cultures of lymphocytes whose proliferation was stimulated with nucleic acids. |
