CopyCutter EPI400 Chemically Competent E. coli, 10 ReactionsClone unstable and toxic sequences in standard plasmids, with high efficiency. Key Features Optimised for cloning toxic or unstable DNA Stabilise toxic inserts in common cloning and expression vectors (pUC and pET type vectors) Clone and maintain challenging sequences at reduced plasmid copy number, then induce to high copy number for DNA recovery Avoid T1 and T5 phage contamination with tonA mutation Choose chemically competent cells for general
