title: Determination of tissue plasminogen activator by an enzyme-immunoassay method.
abstract: The sensitive assay method of tissue plasminogen activator was established by an enzyme-immunoassay method, and discriminates tissue (nonurokinase) type plasminogen activator from urokinase. The sensitivity was 0.1 ng/assay tube, and the plasma concentration of tissue plasminogen activator in normal healthy subjects was 1.22 +/- 0.25 ng/ml. Distribution of tissue plasminogen activator was examined in normal tissue. A melanoma cell line was employed as cell culture medium for determination of tissue plasminogen activator.
