Product name:Human C3c ELISA Kit
Description:
C3 consists of two polypeptide chains (alpha, molecular weight 115 kDa and beta, molecular weight 75 kDa) and is usually present in serum at 1 to 2 mg/L. It is the pivotal protein of the complement system, being central in the classical pathway and the alternative pathway. It is cleaved by the classical pathway convertase C4b2a and the alternative pathway convertase C3bBb, into C3b and C3a. C3c, along with iC3b and C3dg, is formed as a result of C3b inactivation by Factor I and various cofactors. The C3 fragments are eliminated by liver phagocytic cells.
