  • Title: Preparative electroelution of specific protein antigens from Mycoplasma pneumoniae: use in an enzyme-linked immunosorbent assay (ELISA).

    Journal: Ann Inst Pasteur Microbiol; 1988; 139(5):589-603. PubMed ID: 3150937.
    Abstract:
    A rapid, simple and preparative method is described for the recovery of the seven highest molecular weight proteins (HMWP) from Mycoplasma pneumoniae membrane. The yield of proteins obtained was approximately 90%. The method involved the separation of M. pneumoniae proteins by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE), followed by electroelution of HMWP. These eluted antigens were used in an ELISA to measure IgG antibodies in sera from 9 blood donors and 9 patients with M. pneumoniae infection. The specificity of M. pneumoniae HMWP was examined by competition ELISA and immunoblotting with different mycoplasma species encountered in the respiratory tract.
