* Expression in E.coli strains with defects in maintaining the low redox potential of the cytoplasm. Strains carry mutations in thioredoxin reductase (trxB-, ADA494) or glutathione reductase (gor-) or both (Origami starin) and allow disulfide formation in the cytoplasm. Even expression of multiple Ig domains is possible in the Origami strain.
