Description

MegaX DH10B T1R Electrocomp Cells are the highest-efficiency electrocompetent cells available. Improved production processes now guarantee a three-fold greater number of colonies per transformation (>3 x 1010 cfu/µg of pUC DNA), making the MegaX DH10B T1R cells ideal for highly demanding cloning and library construction. They have the same genotype as the widely used DH10B T1R strain, including tonA, which prevents infection by T1 and T5 lytic bacteriophages, and safeguards your valuable clones and libraries.

Using MegaX DH10B T1R cells
MegaX DH10B T1R cells provide highly efficient transformation of methylated DNA, since they lack the E. coli K12 restriction systems (mcrA Δ(mrr-hsdRMS-mcrBC)). The Φ80lacZΔM15 marker provides α-complementation of the β-galactosidase gene, allowing blue/white screening on agar plates containing X-gal or Bluo-gal.
