Supplier:  Hycult Biotech Inc HK35601

C1q forms together with C1r and C1s the C1 macromolecule, the first component of the classical complement pathway. The formation of an antibody–antigen complex (immune complex) is the principal way of activating the classical pathway of the complement system. C1q triggers the activation process when it docks onto antibodies within these immune complexes. In this way, C1q acts to bridge the innate and adaptive immune systems. Interaction of immune complexes with C1q induces a conformational change within the C1 complex, which results in activation of the classical pathway. C1q functions as recognition unit by binding to the heavy chain of IgG or IgM (Fc gamma and Fc micro) provided that the immunoglobulins are bound to their antigen. Furthermore, C1q can bind to apoptotic blebs, where it activates the classical complement pathway and mediates phagocytosis.
