C1q Protein
Purified human C1q protein
Product Specifications
Background
Purified human complement component C1q. Circulating C1q protein is a hexamer of three unique protein subunits (A, B, and C) with molecular weights of 29, 26 and 22 kD respectively. The assembled hexamer contains a central core or stalk, 6 collagen-like domains and 6 globular protein heads. These globular or terminal regions are responsible for the binding of immunoglobulins (IgM and IgG) . As part of the C1 complex (together with two copies each of C1r and C1s) C1q is central to activation of the classical complement pathway.
