DEFINITION

Classification: 530/382

Fibrin or fibrin intermediates, e.g., fibrinogen etc.:

(under subclass 381) Proteins having the structure of fibrin and compounds derived for these by addition to or deletion of parts of the polypeptide structure.

(1) Note. Physical Properties: [figure]

(2) Note. Fibrinogen is a hexamer of two sets of three nonidentical chains linked by disulphide bonds.

(3) Note. Example. Fibrinogen, Fibrinopeptide A (19 residues MW 1,892), antihemophilic globulin 1X, Blood Clotting Factor I, Parenogen.

(4) Note. CA Registry Number: Fibrin [figure]
