SummaryProthrombin products prepared by Seegers procedure induce fibrinolysis when injected intravenously. This property is due to a contaminant denominated Prothrombin Activating Derivative-B, identified as factor XII. The fibrinolytic fraction acco

SummaryWhen bovine thrombin was prepared by one method the N-terminal amino acid was glutamic acid while with another method it was threonine. In urea solution these N-terminal amino acids were removed in association with peptides and the N-terminal

In experiments with purified biothrombin, it was found that strong solutions of sodium citrate or protamine sulfate (0.1% w/v) or purified platelet factor 3 depress the esterase activity and leave the clotting power unaltered. Apparently a depression

SummaryPreparations of bovine platelet cofactor I have been examined according to biophysical methods. In the ultracentrifuge the patterns reveal a major component comprising 86% of the total and two faster moving minor components. The sedimentation

SummaryAn attempt was made to obtain Ac-globulin from bovine plasma. The concentrates contain mostly protein, and phosphorus is also present. The stability characteristics vary from one preparation to another, but in general there was no loss before

Purified prothrombin can be activated in several ways to obtain biothrombin. This thrombin possesses the properties of activating fibrinogen, catalyzing the activation of prothrombin, neuralizing antithrombin, dissolving fibrin clots and has esterase

A method for the purification of platelet cofactor I is described. Platelet cofactor II is first removed from plasma by adsorption on barium salts. The plasma is brought exactly to ph 6.3 for adsorbing the platelet cofactor I on kaolin, from which it

Thrombin that has been acetylated on its free amino group loses its fibrinogen-clotting properties, but when injected intravenously produces a fibrinolytic syndrome. The lytic results compare very closely to those obtained with thrombin administratio

SummaryFactor VIII increase after stress or adrenergic stimulation appears to be justified by ACTH release, which in turn liberates a principle other than steroids, from the adrenal cortex. A substance isolated from adrenal cortex and denominated S3
