Transformation efficiency should be ≥1 x 10 5 CFU/µg pCAMBIA1391z DNA. WebCompetent cells have altered cell walls that allow the DNA to easily pass through it. Some cells need to be exposed to some chemical or electrical treatments to make them competent. Treatment with calcium ions is the standard method for the preparation of these cells. Bacterial cells can also take up DNA through a process called electroporation.
