Preparation and properties of monoclonal antibodies against Mycobacterium tuberculosis.

The above mentioned monoclonal antibodies of idiotype IgG 3/Kappa against TMC 120 and TMC 107 strains of M. tuberculosis were prepared by fusion of mouse myeloma line FO cells with splenocytes BALB/c of mice immunized with complex antigens. These were prepared from the bacterial mass previously inactivated with gamma-rays radiation, and applied without mycobacterial adjuvant agent. Species specificity of both monoclonal antibodies was determined by ELISA testing and dot blot test. The potential use of the mentioned preparations consists in species identifying and taxonomy of mycobacteria, mycobacterial antigen purification and prompt TBC diagnosis (serodiagnosis, identifying of specific antigens in pathological materials.
