title: Fibrin membrane endowed with biological function. IV. Formation of cross-links between fibrinogen (or fibrin) and ribonuclease by transglutaminase.
abstract: Transglutaminase from guinea pig liver catalyzed the formation of cross-links between fibrinogen (or fibrin) and ribonuclease. Using transglutaminase, immoblized ribonuclease was prepared by two separate methods: (1) fibrinogen-ribonuclease conjugates formed by transglutaminase were treated with thrombin to make fibrin membrane bound covalently to the enzyme; (2) fibrin polymer formed from fibrinogen with thrombin was covalently bound to ribonuclease by transglutaminase to make fibrin-ribonuclease conjugates.
