ORDER INFORMATION

Endura™ Competent Cells include Control DNA and Recovery Medium, and are packaged as SOLOs (1 transformation per tube) or DUOs (2 transformations per tube) as indicated. Endura Electrocompetent cells are provided in DUOs format only. Recovery Medium is also available separately. The specified transformation efficiencies are with pUC DNA, unless indicated otherwise.

PLEASE NOTE: Bulk quantities (10 times larger than the largest retail package size below) and/or custom packaging are available at very attractive prices for all Lucigen Competent Cells. Please contact Lucigen.

Description

Conserve clones that contain unstable sequences!

Maintain unstable DNA. Lucigen’s Endura Competent Cells are a commonly used strain for cloning sequences that suffer unwanted recombination events in other strains. Clones with inverted repeats or other sequnces prone to recombination are commonly found in retroviral genes, and require cells such as Endura to be propagated stably.

Excellent value and efficiency! Switch to Endura cells today and experience a higher level of efficiency and a savings in your cloning budget.

Chemical or Electrocompetent. Whichever method of transformation you prefer, Lucigen can give you better efficiency and/or better prices.
