because there was a possibility that activated factor xiii ( factor xiiia ) might stabilize a platelet-fibrinogen aggregate through its crosslinking action , we have isolated plasma factor xiii , activated it , and studied the effect of factor xiiia at a concentration of 3.3 micrograms/ml on aggregation and 125i-fibrinogen binding of rabbit platelets stimulated with 9 microm adp .
