Abstract:
A simple spectrophotometric method for the quantitating of the clot promoting activity of thromboplastin in commercial preparations was developed. Thromboplastin activities were proportional to the maximum rate of clot formation. This was calculated from curves of absorption change during the coagulation of plasma coagulation control. The clot-promoting effects of thromboplastin in commercial preparations varied widely when assayed by this method.
