title: The combined IGG, IGM and IGA peroxidase conjugate can facilitate determination of immune complexes by CIF-ELISA and anti-C3 ELISA.
abstract: To determine the levels of circulating immune complexes (CIC) in normal and patients sera, CIF-ELISA and anti-C3 ELISA were performed. Immune complexes containing different antibody isotypes were detected simultaneously by the combined anti human IgG, IgM and IgA peroxidase conjugate as detecting antibody. The results obtained confirm the higher CIF-ELISA sensitivity, specificity and reproductivity compared to anti-C3 ELISA and provide good evidence to justify the use of CIF-ELISA as a screening test for CIC assessment.
