Human plasma and serum were obtained from blood of resting persons. Plasminogen was determined by activation with the optimal amount of streptokinase. As in the majority of cases no significant difference was found between the proteolytic activity of plasma and serum, a blood clot cannot contain more plasminogen than that present in the volume of serum included.
