Acella™ Competent Cells from Edge Bio allow you to clone and express in one novel strain. Available in either chemically competent 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. Plasmid DNA can be isolated after only 3-6 hours of growth. Acella™ Chemically Competent Cells are also available in a pLysS version that will allow you to express otherwise toxic proteins. Edge Bio guarantee Transformation Efficiencies of ≥2x108 cfu/µg pUC19 for chemically competent cells and ≥1010 cfu/µg pUC19 for electrocompetent cells.
