Description

Perform plasmid rescue for transposition mutants created with the EZ-Tn5 Transposome Kits.

Each product contains 5 tubes each containing 100 µL of electrocompetent cells, which is enough cells for 10 electroporations. A control vector containing and R6Kγori is also included with each product.

Key features

  • Rescue cloning of EZ-Tn5 transposed elements
  • Propagate plasmids tagged with the EZ-Tn5 Insertion Kit

Product information

The TransforMax™ EC100D™ pir+ Electrocompetent E. coli and TransforMax™ EC100D™ pir-116 Electrocompetent E. coli each constitutively express the π protein (the pir gene product) for replication of plasmids containing the R6Kγ origin of replication (R6Kγ ori). The cells are derived from Epicentre's TransforMax™ EC100™ Electrocompetent E. coli by P1 phage transduction with a strain containing the pir+ or pir-116 gene linked to a dihydrofolate reductase (DHFR) marker.

The TransforMax EC100D pir+ cells will maintain R6Kγ ori containing plasmids at approximately 15 copies per cell, 1 for cloning of potentially toxic or unstable DNA sequences. The TransforMax EC100D pir-116 cells are for high-copy propagation of up to 250 rescue plasmid copies per cell. 1

Benefits

  • Accepts large clones for unbiased propagation and stability of large rescue clones.
  • lacZΔM15 for blue/white screening of recombinants.
  • Restriction minus [mcrA, Δ(mrr-hsdRMS-mcrBC)] enables efficient cloning of methylated DNA.
  • Endonuclease minus ( endA1) to ensure high yields of DNA.
  • Recombination minus ( recA1) for greater stability of large cloned inserts.
