Complement proteins bound to circulating immune complexes (CIC) were measured in samples from 35 systemic lupus erythematosus (SLE) patients. Levels of C1q, C3, and C4 bound to CIC were measured using enzyme-linked immunosorbent assay (ELISA). The concentration of complement proteins present on CIC is represented as ng/ml. The C3 and C4 bound to CIC are represented on the left y axis while C1q bound to CIC are represented on the right y axis. The C3 levels were the highest on CIC followed by the C1q and C4 amounts.
