| Abstract: | Purpose To characterize defibrase enzyme isolated from the venom of Agkistrodon ussuriensis emellaov. Methods Defibrase was purified by one-step affinity chromatographic method, and the purified enzyme was analyzed by HPLC and SDS-PAGE, respectively. Results The enzyme was purified with a high yield and high purity. SDS-PAGE data indicated that the purified enzyme was a single band, and its molecular weight was about 36 000. The specific enzymatic activity was measured as 4 800 u/mg. Conclusion The method for purifying defibrase by one-step affinity chromatographic method is convenient and efficient. |
