 AB    OBJECTIVE: To visualize HIV-1 protein-antibody interactions and to study
       its distributions on the surface of latex particles. METHODS:
       Polysterene latex microspheres (D-08 micron) with adsorbed rabbit
       antibodies against HIV-1 are used and visualizations of antibodies are
       carried out by immuno-EM technique. RESULTS: Latex microspheres are
       mixed with solutions with different concentrations of virus antigen and
       several minutes after agglutination starts, microspheres are placed on
       EM-grids and proceeded with gold antirabbit conjudate. Different degrees
       of conjugate - antibody interaction and antigenes distributions on the
       surface of microspheres are observed. DISCUSSION AND CONCLUSIONS: It is
       supposed uneven conjugate-antibody distributions depend on properties of
       latex surface.
