title: [Immobilization of the human plasmin light chain and analysis of its complexes with streptokinase].
abstract: The heavy and light chains of human plasmin were separated by affinity 1-lysin-cellulose column chromatography. The S-carboxymethyl light chain derivative of human plasmin was imobilized by aminogroups by the insoluble matrices. Insoluble derivatives cf plasmin light chain retain an insignificant proteolytic activity, human plasminogen activator activity and capacity to form complexes with streptokinase. The activator activity of the immobilized light chain-streptokinase complex increases 5-10-fold with respect to the human plasminogen. When adding the light chain preparation to immobilized streptokinase its activator activity relative to the human plasminogen is twice as high. The both complexes: immobilized light chain-streptokinase and light chain-immobilized streptokinase are stable and may be reused for plasminogen activation.
