IL-21 PRODUCTION IN PROKARYOTIC HOSTS |
摘要 |
The expression vectors and methods using an E. coli expression system for the large scale production of IL-21 are described. The vectors utilize the IL-21 coding sequence with specific changes in nucleotides in order to optimize codons and mRNA secondary structure for translation in E. coli. Using the expression vectors, the IL-21 gene was produced in E. coli to a level of greater than 1 g/L in fed batch fermentation. Also included are OmpT deficient E. coli strains transformed with an IL-21 expression vector.
