Abstract
An immunoassay method utilizes antigen tagged, enzyme encapsulating liposomes which are immunospecifically ruptured in the presence of cognate antibody and active complement. A homogeneous phase reaction occurs with the antibody and complement acting to release the enzyme if an immunospecific antigen-antibody complex is formed at the surface of the liposome. The positions of the antigen and antibody can be reversed.
