Thermo Scientific DH10B Competent Cells are high efficiency, chemically competent E. coli cells. The DH10B strain is suitable for cloning DNA containing methylcytosine, 5-hydroxymethylcytosine, and methyladenine, allowing both prokaryotic and eukaryotic genomic DNA to be cloned efficiently. These cells are ideal for the construction of gene banks or for the generation of cDNA libraries using plasmid-derived vectors. The φ80dlacZΔM15 marker provides α-complementation of the β-galactosidase gene from pUC or similar vectors to allow blue/white colony screening on bacterial agar plates containing Bluo-Gal or X-Gal.
