Composition<unk>  comes in two vials, respectively containing *<unk> ogen: lyophilised pooled human concentrate and * thrombin: This used to be of bovine origin; modern formulations contain human thrombin. The two components are mixed immediately before application. The formulations also contain calcium salts. Formulations from different manufacturers may also contain aprotinin,<unk> ectin, plasminogen, and factor XIII. Factors affecting structure Factors that influence dimensional structure of<unk>  gel giving rise to fine or coarse gel: # Changing concentration of<unk> ogen # Changing concentration of thrombin – increased concentration increases ultimate tensile strength and Young modulus of gel # Changing concentration of calcium # pH # Temperature
