Provides stable replication of high copy number plasmids. The genotype of TOP10 cells is similar to that of DH10B™ strain.

  • hsdR for efficient transformation of unmethylated DNA from PCR amplifications
  • mcrA for efficient transformation of methylated DNA from genomic preparations
  • lacZΔM15 for blue/white color screening of recombinant clones
  • endA1 for cleaner preparations of DNA—get better results in downstream applications due to elimination of nonspecific digestion by Endonuclease I
  • recA1 for reduced occurrence of nonspecific recombination in cloned DNA
  • Bacterial/Yeast Strain: TOP10
