title: Isoelectrophoretic characterization of protein antigens present in mycobacterial culture filtrates and recognized by monoclonal antibodies directed against the Mycobacterium bovis BCG antigen 85 complex.
abstract: Nine monoclonal antibodies (MoAbs) were produced against Mycobacterium bovis BCG antigen 85 complex. Using isoelectric focusing combined with Western (immunoblot) blot analysis, antigenically related proteins could be identified in culture filtrates from M. tuberculosis, M. bovis, M. Kansasii, M. avium, M. xenopi, M. gordonae, M. fortuitum, M. phlei and M. smegmatis. Most of the MoAbs were found to be broadly cross-reactive between the various mycobacterial species, albeit some minor differences were observed. These MoAbs reacted generally, in each species, with different components. One MoAb (VID1-14) was found to be specifically directed only against antigen 85B from M. bovis, M. tuberculosis and M. kansasii.
