[Use of enzyme-antibody immune complexes in serological analysis]

In model experiments with simulation of rabbit immune response to mouse IgG and antibody production in echinococcosis patients the indirect enzyme-linked immunosorbent assay has been several times more sensitive with peroxidase-antiperoxidase and catalase-anticatalase complexes than with enzyme-antiglobulin chemical conjugates. The immune complexes have been found to retain their activity for 6 months and longer.
