ECOSTM Blue Competent Cells (XL1-Blue)

(download PDF)

This strain is the most popular for blue/white screening. It is also an excellent host strain for routine cloning application using plasmid or lambda vectors. XL1-Blue cells are tetracycline resistant. XL1-Blue cells are endonuclease (endA) deficient, which greatly improve the quality of miniprep DNA, and are recombination (recA) deficient, improving insert stability. The hsdR mutation prevents the cleavage of cloned DNA by the EcoK endonuclease system. The lacIqZΔM15 gene on the F’ episome allows blue-white color screening.

 

ECOSTM Blue Competent Cells are chemically competent and have been developed using a novel chemical preparation. ECOSTM technology makes the cell highly efficient for DNA uptake.
