Beschreibung

Allgemeine Beschreibung

The STEADY Chemically 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 this product to be propagated stably.
