Intact Genomics (ig) XL1 Blue Max Electrocompetent E. coli cells offer the highest transformation efficiency ≥5 x 10^10 cfu/µg plasmid DNA which is ideal for applications such as cDNA or gDNA library construction. These cells can be used to prepare high-quality plasmid DNA, and single strand rescue of phagemid DNA and Blue/white screening. igXL1 Blue Max cells provide transformation efficiencies that are significantly higher than any competitor’s similar product.ig XL1 Blue Max Electrocompetent Cells features: - tetracycline resistant. - endonuclease (endA) deficient, which greatly improves the quality of miniprep DNA. - recombination (recA) deficient, improving insert stability. Cleavage of cloned DNA by the EcoK endonuclease system is prevented by the hsdR mutation.
