Abstract: | An affinity adsorbent, benzamidineSepharose 4B, was used to separate and purify thrombinlike enzymes. The paminobenzamidine as a specific ligand was coupled to the matrix-Sepharose 4B. The recombinant thrombinlike enzyme-defibrase was used as a model in order to evaluate the efficiency of this biospecific affinity adsorbent. The homogeneity of the enzyme preparation was comfirmed as one band on sodium dodecyl sulfatepolyacrylamide gel electrophoresis. |
