ClearColi BL21(DE3) Electrocompetent Cells
Eliminate endotoxin at the source with this unique engineered E. coli strain for low-endotoxin protein expression.
Eliminate endotoxin at the source with this unique engineered E. coli strain for low-endotoxin protein expression.
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.
