Description One Shot® TOP10 Chemically Competent E. coli, 20rxns
Detail

TOP10 E. coli are provided at a transformation efficiency of 1 x 109 cfu/µg supercoiled DNA and are ideal for high-efficiency cloning and plasmid propagation. They allow stable replication of high-copy number plasmids. The genotype of TOP10 Cells is similar to the DH10B™strain, and offers the following features:

 

 

 

 

 

 

  • hsdR for efficient transformation of unmethylated DNA from PCR amplifications
  • mcrA for efficient transformation of methylated DNA from genomic preparations
  • lacZM15 for blue/white color screening of recombinant clones
  • endA1 for cleaner preparations of DNA and better results in downstream applications due to the elimination of non-specific digestion by Endonuclease I
    recA1 for reduced occurrence of non-specific recombination in cloned DNA
    One Shot® TOP10 Kits are available with either chemically competent or electrocompetent E. coli to fit your specific transformation needs. TOP10 E. coli are also available in the high-throughput MultiShot™ format.
