title: Homogeneous immunoassay of polyclonal antibodies by use of antigen-coupled liposomes.
abstract: Anti-cytochrome c and anti-myoglobin antibodies were assayed by use of immunoliposomes coupled with the antigens. Addition of complement under the existence of the antigens. Addition of complement under the existence of the antigen-antibody complex on the surface of the liposome caused lysis of the liposomes, which was proportional to the amount of the antigen-antibody complex formed as well as the concentration of complement added. Thus, the degree of marker release depended on the average association constant and also on its heterogeneity of the polyclonal antibodies, which shows that the results assayed by this method are correlated to the antibody ability to form the antigen-antibody complex.
