A number of hybridomas against different determinants of R. prowazekii were obtained by hybridization of splenocytes from BALB/c mice immunized with whole cells or soluble antigens of the organism. Some of the monoclonal antibodies bound to thermolabile species specific protein of R. prowazekii and did not react with R. mooseri antigens (monoclonal(More)
As the result of immunization of BALB/c mice with the commercial preparation of typhus vaccine and R. prowazekii corpuscular antigen, in 29.2% and 40.3% of cases (respectively) the appearance of hybridomas synthesizing monoclonal antibodies (McAb) to different autologous structures (skin and thymic epithelium, cell nuclei, conjunctive tissue structures and(More)
R. prowazekii antigens have been tested with the use of monoclonal antibodies (McAb) to different epitopes of the microorganism. As revealed in these tests, McAb B4/4 and A-3/D, active against species-specific thermolabile antigen, interact with protein having a molecular weight of 90-120 KD. McAb C5/2, active against thermostable group antigen common with(More)
The results of this investigation indicate that preparations obtained on the basis of monoclonal antibodies have proved to be suitable for the detection of R. prowazekii antigens in the natural carrier of typhus when used in all types of the enzyme immunoassay; of these, the assay made by the capture method has been found to possess the highest sensitivity.(More)
A number of hybridomas to different R. prowazekii determinants were obtained by the hybridization of spleen cells of BALB/c mice immunized with R. prowazekii corpuscular and soluble antigens. Some of the monoclonal antibodies (McAb) reacted with R. prowazekii thermolabile species-specific protein and did not react with R. typhi antigens (McAb of batches(More)
Immunization of BALB/c mice with Rickettsia prowazekii antigens, Bordetella pertussis toxin and Legionella pneumophila cytolysin induces the synthesis of IgM autoantibodies of different specificity. Among monoclonal antibodies, multispecific antibodies with a wide reactivity spectrum have been found to make up high percentage (30-80%). Monoclonal antibodies(More)
