Rabbit Human C1q Antibody

Precipitating polyclonal rabbit antiserum to the C1q subunit of C1 component of human complement. C1 component of human complement is a complex of three glycoproteins: C1q, C1r and C1s. C1q has a molecular weight of 492.000 and is present in plasma in an average concentration of 80 mg/ml. It consists of a complex of 18 polypeptide chains of three different types, A, B and C; 6 of each type. The subcomponent C1q is responsible for the binding of C1q to immunocomplexes an membranes via the Fc portion of the immunoglobulin. The subunit C1q is isolated as a homogenous protein for use in antiserum production. Freund's complete adjuvant is used in the first step of the immunization procedure.
