[The production of antibody-producing hybridomas to the Lassa virus].
The work deals with obtaining hybrid cell lines producing monoclonal antibodies to Lassa arenavirus. To obtain preparations for the screening of hybridomas by indirect immunofluorescence techniques, the dynamics of the accumulation of Lassa virus antigen in cell cultures Vero and 4647 was studied. The maximum accumulation of the virus antigen in Vero cells was shown to occur on day 3 after inoculation with a dose of 1.0 PFU/ml. The influence of different doses of gamma radiation on the infectious and antigenic activity of the virus was studied. The expediency of using a dose of 20.0 kGy for the irradiation of the virus was shown. The optimum schedule for the immunization of BALB/c mice was worked out, which made it possible to obtain activated mouse spleen cells used for the construction of hybridomas. The capacity of hybrid cells, injected into syngeneic mice, for the generation of tumors was shown.
