  • Title: Enzyme-linked immunosorbent assays for the detection of Neisseria gonorrhoeae specific antibodies.

    Journal: Can J Microbiol; 1978 Nov; 24(11):1300-5. PubMed ID: 105793.
    Abstract:
    An indirect enzyme-linked immunosorbent assay (ELISA) using rigid polystyrene microtiter plates was adapted to detect specific gonococcal antibodies against outer membrane-complex antigens extracted from Neisseria gonorrhoeae. The concentration of antigen to obtain maximum coating of the well was 10 micrograms protein per millilitre. The optimal binding of the primary antibody and enzyme-conjugated antimmunoglobulin was achieved after 1 h at 37 degrees C. Under these conditions using gonococcal antisera, no cross-reactivity was observed with outer membrane antigens extracted from Neisseria meningitidis serogroups B, C, X, Y, and W135. Neisseria meningitidis serogroup A demonstrated low levels of cross-reactivity. All the non-pathogenic Neisseria spp. tested were negative (absorbance value at 400 nm/30 min less than 0.15). The reaction of immune serum against outer membrane complex absorbed to the microwells was completely inhibited with soluble-specific antigen but not with purified N. gonorrhoeae lipopolysaccharide. Quantitative inhibition permitted the measurement of low levels of antigen (0.5 microgram/ml). The detection of N. gonorrhoeae antibody with ELISA is specific and highly sensitive.
