Chemically Competent Cells For Lac Based Protein Expression

Chemically Competent Cells For Lac Based Protein Expression

Cambridge Bioscience offers competent cells for tightly regulated control of protein expression whilst maintaining high yield in systems using the lac operator. Combining exceptional efficiency and a simple, reliable heat-shock procedure for chemical transformation, the HI-Control™ competent cells provide high protein yields with reduced leaky expression from small amounts of plasmid DNA.

Benefits of Using the HI-Control™ Competent Cells
• High protein yields - HI-Control™ 10G ≥1×109 cfu/µg & HI-Control™ BL21(DE3) ≥1×107 cfu/µg
• High efficiency - excellent transformation from small amounts of DNA
• Simple, reliable procedure
• Tightly regulated protein expression
• Reduced leaky expression
• Compatible with T7-lac and other lac based promoters
• Complete kit
