Your choice of two packaging formats
High efficiency: over 1 × 10⁸ cfu/µg (chem) or 1 × 10¹⁰ cfu/µg (electro)
Excellent value

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.
