assay procedures usually involve the activation of the plasminogen to plasmin using an activator such as streptokinase ( sk ) or urokinase ( uk ) and a major problem involves the establishment of a properly-timed plasminogen-activator ratio to fully express the plasminogen as the active enzyme plasmin ( gaffney , p.j . et al . activation of plasminogen as a feature of its assay . haemostasis 1977 , 6 , 72-78 ) .
