Plasminogen activators in alveolar bone in man.

Abstract

Plasminogen activators in alveolar bone in man was studied in quenching experiments by a fibrin slide technique with addition of monospecific antibodies against tissue plasminogen activators (t-PA) and urokinase (u-PA). The plasminogen activator activity was quenched in the slides with anti-t-PA. No quenching was observed in the slides with anti-u-PA. This does not exclude the possibility that enzymatically inactive pre-urokinase is present.
