Antigen–antibody reactions - Armstrong - 2008 - ISBT

09/05/2008· C1 is a large molecule consisting of C1q, C1r and C1s that when coined with Fc, inter-react and cause further changes and cleavage of C1. The complex C1 component is stabilized in the presence of calcium ions (Ca ++), without which C1 dissociates and becomes inactive. (This explains why anticoagulants that chelate calcium are anti-complementary.)
