Opis

Opis ogólny

Native, human C8 complement component. Glycoprotein composed of three non-identical subunits of M.W. 64 kDa (α), 64 kDa (β), and 22 kDa (γ). Present in normal human serum at 55 µg/ml. On activation of complement via either the classical or alternative pathway, C5 is cleaved into C5a and C5b fragments. The nascent C5b fragment binds to C6, C7, and C8 resulting in formation of the C5b-8 complex on target surfaces. Each membrane-bound, hydrophobic C5b-8 complex combines with three to six C9 molecules to complete the assembly of the lytic C5b-9 complement membrane attack complex (MAC).
