Competent Cells for Genomic & cDNA Library Construction
OminMAX™ and DH10B™ competent cells have eliminated mcrA, mcrBC, mrr, and hsdRMS restriction systems to allow construction of more representative genomic libraries. |

Note: Both the TOP10 and Mach1 competent cells have: the lacZ∆ M15 for blue/white color screening of recombinants, the recA mutation to minimize non-specific recombination in cloned DNA, endA1 mutation for increased plasmid yield and quality, and the hsdR mutation for efficient transformation of unmethylated DNA from PCR amplifications.
