MAX Efficiency® DH10B™ Competent Cells
MAX Efficiency® DH10B™ Competent Cells are highly efficient E. coli, perfect for most applications. DH10B™ E. coli are available in both electrocompetent and chemically competent formats. The high transformation efficiency makes them ideal for generating cDNA or genomic libraries. High-efficiency transformation is seen with plasmids 150 kb in size. The versatile DH10B™ genotype has the following features:
• lacZ for blue/white screening of recombinant clones
• Elimination of mcrA, mcrBC, mrr, and hsdRMS restriction systems to allow construction of more representative genomic libraries
• A1 mutation to increase plasmid yield and quantity
