The expression was effective in both SMS300 and SMS118, but higher yield of 7. 1 mg/L was observed in SMS300 compared with 2. 1 mg/L in SMS118. Western blot showed that the recombinant protein could be effectively secreted into the culture medium as a 58 ku peptide, and could be de-graded into two peptides of 37ku and 21ku.展开更多
