title: Fibrinolytic activity of allergenic preparations: an artefact due to enzyme contamination.
abstract: Some of the common allergenic preparations induced lysis of fibrin plates in vitro. Esterolytic and proteolytic activity was found associated with these preparations. All activities were abolished by heat treatment. It is concluded that allergens do not activate human plasminogen and that in vitro fibrinolysis is due to enzyme contamination.
