ElectroMAX™ Stbl4™ Competent Cells
ElectroMAX™ Stbl4™ Competent Cells are specifically designed for cloning unstable inserts. As electrocompetent cells, they have one of the highest transformation efficiencies available (>5×109 cfu/µg), making them ideal for generating cDNA and genomic libraries and for cloning unstable inserts. These electrocompetent E. coli:
• Are ideal for cloning unstable DNA—stabilizes direct repeat and retroviral sequences
• Permit efficient cloning of methylated genomic DNA
• Support blue/white screening
• Are designed to deliver high-yield plasmid preparations for downstream applications
• Provide transformation efficiencies of >5×109 cfu/µg
Propagating unstable and large DNA with high transformation-efficiency cells
Many competent cell strains have the recA1 genotype, which reduces recombination. However there are some instances when the DNA that you are trying to clone is still unstable in such cells, perhaps due to the presence of inverted or direct repeats, or GC-rich
