Native Human Complement C4c

Cat.No.: C4-195H
Description: Complement C4 (C4) plays a central role in both the classical and lectin pathways of complement activation, with levels in human plasma ~0.4 mg/ml. C4 circulates in human plasma as a heterotrimer of 205,000 Da in plasma. The three disulfide-linked chains have molecular weights of 93 (alpha), 75 (beta), and 32 (gamma) kDa, although C4 is readily processed to smaller fragments (C4a, C4b, C4c), as evidenced by the molecular weight description below.
