The limitations of the technique were clearly defined at the outset. Although the C1q reagent reacted preferentially with complexed antibody, regardless of the antigen involved, it did not differentiate antigen-antibody complexes from nonspecifically aggregated immunoglobulins. Moreover, it reacted with various polyanions. Nonetheless, this approach was attractive to clinical investigators, because in most human diseases in which immune complexes had been implicated in the pathologic process the antigen involved was unknown. Hence,...References1. AGNELLO V, WINCHESTER R, and KUNKEL H. Precipitin reactions of the C1q component of complement with aggregated ᵧ-globulin and immune complexes in gel diffusion.
