Abstract

A novel chemiluminescence immunoassay which combines microparticles and microemulsion is described. The method is based on a specific interaction of an antibody with an antigen preadsorbed onto fluorescer (perylene) microparticles (mean diameter 0.8-1.6μm). Dissolving the particles in a microemulsion-forming mixture containing bis(2,4,6-trichlorophenyl) oxalate in toluene (oil phase) and H2O2 in Triton X-100 (surfactant)/2-butanol (cosurfactant)/water leads to chemiluminescence. The dependence of the chemiluminescence intensity on the concentrations of antigen, antibody and fluorescer, as well as the kinetics of the chemiluminescence decay, were studied.
