title: Fibrinogen and the ultralong-range interaction of human erythrocytes.
abstract: Fibrinogen, purified by a new method, does not transmit the ultralong-range interaction of erythrocytes. It can be converted into a transmitter by the addition of a preparation of clotting factors used clinically in the treatment of hemophilia B. It is suggested that the addition of the clotting factors induces a conformational change in fibrinogen, which can then polymerize.
