Mach1 T1 Phage-Resistant Chemically Competent E. coli are the fastest growing chemically competent cells currently available. Doubling time is approximately 50 minutes, compared to >74 minutes for other cloning strains. Mach1 colonies enabling you to plate and pick colonies the same day. Perform mini-preps after only four hours of growth from an overnight colony—saving an entire day in your experiments.

  • Minimizes nonspecific recombination in cloned DNA (recA)
  • Offers resistance to T1 and T5 phage (tonA)
  • Yields cleaner preparations of DNA and better results in downstream applications due to the elimination of nonspecific digestion by Endonuclease I (endA1)
  • Provides efficient transformation of unmethylated DNA from PCR amplifications (hsdR)
  • Allows blue/white screening of recombinant clones (lacZΔM15)
  • Two formats to choose: Convenient One Shot format provides single-use, 50μL aliquots that eliminate efficiency-zapping, freeze-thaw cycles and money wasted on unused cells
  • MultiShot StripWell format allows rapid, high-throughput transformation in a 96-well stripwell plate, which allows as few or as many transformations as needed without wasting reagents

Not high-throughput compatible (Manual)
