Study on the Optimal Isolation Technique of Superoxide Dismutase from Pig and Bovine Blood Block

Double, three factor-test and orthogonal designs were employed to study the effect of protective agent, membranolytic agent, activating agent, denaturalization temperature and denaturalization time on SOD extracted from pig and bovine blood block. The results of double and three factor-tests show that the variance between pig and bovine blood block was obviously significant (P
