Stabilise toxic sequences behind T7 or lac-based promoters with this strain containing a LacI repressor, providing tight control over leaky expression.
Clone large inserts in standard plasmids, avoid T1 and T5 phage contamination, and control copy number of CopyControl vectors.
Induce high-level protein expression from T7 promoters with tight control over leaky expression, using this strain containing a LacI repressor.
Optimised formulation for ensuring stability and high-efficiency transformation of protein expression clones.
Induce plasmid copy number in CopyCutter EPI400 strain, for high plasmid yields.
Construct larger, more complex phage display libraries with highest efficiency cells. This amber suppressor strain can be used for phage display and protein expression.
High efficiency F-control strain for phage display applications.
Express difficult or toxic proteins using standard E. coli T7 expression vectors using these unique strains. Also available in chemically competent format.
Construct larger, more complex phage display libraries with highest efficiency cells. SS320 is a non-amber suppressor strain used for phage display.
