The in vivo metabolism of purified third component of complement labeled with 125-iodine (C′3-125I) was studied in normal subjects and in patients with acquired hemolytic anemias. 27 such studies were performed; in addition, three studies were performed using C′3i, the biologically inactive reaction product of C′3.
