Detailed information about E. coli expression vectors
pASG-IBA vectors

- High-level expression in E. coli, also for toxic proteins
- Tightly regulated expression due to anhydrotetracycline (AHT) inducible tetA promoter/operator
- Option for periplasmic expression due to ompA signal sequence
- No catabolite repression - no influence of medium components
- Not influenced by the genetic background – wide choice of E. coli expression strains
- Inexpensive induction with AHT.
pPSG-IBA vectors

- High-level expression in E. coli by bacteriophage T7 promoter
- High-level transcription by T7 RNA polymerase in BL21 strains
- High-level expression of non-toxic proteins
- Induction by IPTG
- Suitable for in vitro transcription/translation
For recombinant protein expression in E. coli, vectors with the Tet promoter (pASK-IBA), protease cleavage site (Factor Xa) and with chloramphenicol resistance gene are available.
