Acella™ Competent Cells allow you to clone and express in one novel strain.  Available in either chemically or electrocompetent cells, the Acella™ strain is a BL21-derivative that features complete deletions of the endA and recA genes, eliminating degradation and recombination of DNA.  Acella™ Competent Cells combine the characteristics of a superior cloning strain with elements of a regulated protein expression system to take you from ligation to expression faster than any other strain.  Acella™ Chemically Competent Cells are also available in a pLysS version that will allow you to express otherwise toxic proteins.

• Guaranteed Transformation Efficiencies – ≥ 2x10⁸ cfu/µg pUC19 for chemically competent cells and ≥ 10¹⁰ cfu/µg pUC19 for electrocompetent cells.
• Advanced derivative of a BL21 (DE3) strain – Characteristics of a superior cloning strain with elements of a regulated protein expression system.
• Eliminates multiple transformations – Ligation to expression faster than any other strain.
• High Quality Plasmid DNA – Complete deletions of endA and recA genes eliminate degradation and recombination of DNA.
• High Level of Protein Expression – Lack of ompT and Ion proteases improves the stability of synthesized proteins.
• Fast Growth – Isolate plasmid DNA after only 3-6 hours of growth.
