Monoclonal antibodies to Treponema pallidum: recognition of a major polypeptide antigen.
نویسندگان
چکیده
Hybridomas secreting monoclonal antibodies that reacted with a 45 000 dalton surface polypeptide and major immunogen of T pallidum were produced. This polypeptide was also found in T pertenue but not in T hyodysenteriae or T phagedenis biotype Reiter.

Molecular cloning and characterization of the 15-kilodalton major immunogen of Treponema pallidum.
Pathogen-specific membrane immunogens of Treponema pallidum subsp. pallidum (T. pallidum) have been identified previously by phase partitioning with the nonionic detergent Triton X-114. One of these antigens, a 15-kilodalton (kDa) polypeptide, is expressed in relatively small quantities in T. pallidum but is highly immunogenic in both human and experimental syphilis. The native T. pallidum anti...
متن کاملDevelopment and evaluation of a monoclonal antibody inhibition enzyme linked immunosorbent assay to diagnose syphilis.
A highly specific inhibition enzyme linked immunosorbent assay (ELISA) using murine monoclonal antibodies to treponemes has been developed to diagnose syphilis. The monoclonal antibodies used in this study were reactive to antigens of both Treponema pallidum and Treponema pertenue and not to antigens of non-pathogenic treponemes. Inhibition of the binding of monoclonal antibody to the treponema...
متن کاملFibronectin mediates Treponema pallidum cytadherence through recognition of fibronectin cell-binding domain
The specificity of the interaction between Treponema pallidum and fibronectin was demonstrated. Treatment of host cells with only antifibronectin sera and not anticollagen or antilaminin sera, inhibited treponemal cytadsorption. Incubation of fibronectin-coated coverslips with monoclonal antibody to the cell-binding domain of fibronectin reduced treponemal attachment to the same extent as antif...
متن کاملSensitivity and specificity of monoclonal antibodies directed against antigenic determinants of Treponema pallidum Nichols in the diagnosis of syphilis.
Murine anti-Treponema pallidum monoclonal antibodies were employed in studies on sensitivity and specificity of binding to examine their potential for use in the detection of low numbers of pathogenic treponemes present in various body fluids. Monoclonal antibodies were used as a primary antibody source in a solid-phase immunoblot assay system. All monoclonal antibodies assayed were capable of ...
متن کاملMonoclonal antibody with hemagglutination, immobilization, and neutralization activities defines an immunodominant, 47,000 mol wt, surface-exposed immunogen of Treponema pallidum (Nichols)
Radioimmunoprecipitation (RIP) analyses performed on 125I-surface-labeled Treponema pallidum cells using various immune sera revealed the presence of six major surface antigens (immunogens) with apparent molecular weights of 47 K, 36 K, 34 K, 32 K, 29 K, and 13 K. Among these, the 47 K surface antigen was most abundant. Radioimmunoprecipitation assays using 125I-labeled T. phagedenis biotype Re...
