Description

JM109 is a K strain that is recA- and endA- to minimize recombination and improve the quality of plasmid DNA. In addition, the cells carry the F' episome, which allows blue/white screening.

  • Ready-to-Use Competent E. coli Cells for Recombinant Cloning and Subcloning
  • Cells are ready to use—no preparation time necessary
  • Transformation efficiencies guaranteed
  • No worries about undesirable recombination events (recA- mutation), and no nuclease carryover in miniprep DNA (endA- mutation)
