For your more demanding cloning needs, we offer the EB10B Electrocompetent cells which are a derivative of the DH10B strain.  EB10B cells boast very high transformation efficiencies that result in a higher number and greater representation of clones, making EB10B cells ideal for library construction.  Their high efficiency and affordability make them the cells of choice for limiting amounts of DNA.

• Guaranteed Transformation Efficiencies – ≥ 10¹⁰ cfu/µg pUC19
• High Quality Plasmid DNA – Mutations of endA and recA genes increase insert stability and improve the quality of plasmid DNA
• Supports Blue/White Screening – Through β-galactosidase complementation
• T1 and T5 bacteriophage resistant – Contains the tonA gene
• Wide range of applications – cDNA, BAC, cosmid, and shotgun libraries. Large plasmids, mutagenesis, routine subcloning, ligated genomic DNA, and methlyated cDNA.
