Hi Nick, Some success has been reported for large soluble proteins using the C41(DE3) and C43(DE3) *E. coli* strains (see the paper by Miroux & Walker). Also you can try another promoter/expression system , the pBAD expression system based on arabinose induction.
Hope this helps. Best -- Pascal F. Egea, PhD Assistant Professor UCLA, David Geffen School of Medicine Department of Biological Chemistry 314 Biomedical Sciences Research Building office (310)-983-3515 lab (310)-983-3516 email pe...@mednet.ucla.edu
