title: Adsorption of fibrinogen and fragment D of fibrinogen onto the insolubilized alpha-chain of fibrin.
abstract: After thrombin treatment insolubilized fibrinmonomer, which is obtained from insolubilized fibrinogen covalently bound to agarose, adsorbs soluble fibrin and its derivatives from solutions. The immobilized proteins are attached to the agarose by the 'A' alpha-chain. After reduction of the disulfide bridges the beta- and gamma-chains can be removed from the agarose. After thrombin treatment the immobilized alpha-chain adsorbs fibrinogen and fragment D. To some extent the beta- and gamma-chain do not seem necessary for the adsorption. The amount adsorbed increases, when thrombin treatment of the insolubilized protein follows the reduction process. This may indicate that the fibrinopeptides 'A' of the insolubilized alpha-chain are better accessible after the removal of the beta- and gamma-chains.
