Highest-efficiency electrocompetent cells
MegaX DH10B™ T1R Electrocomp™ Cells are the highest-efficiency electrocompetent cells available (Figure 1), with a guaranteed three-fold greater number of colonies per transformation (>3 x 1010 cfu/μg of pUC control DNA). They are ideal for highly demanding cloning and library construction applications. MegaX cells have the same genotype as the widely used DH10B™ T1R strain, including tonA to prevent T1 and T5 lytic phage infection and safeguard your valuable clones and libraries; however, they are manufactured using an improved process that results in a significantly higher transformation efficiency. Available in the bulk Electrocomp™ format.
