This exercise demonstrates the use of competent Escherichia coli (E. coli) cells in the take-up of plasmids to cause their transformation. The strain used in this exercise is JM83 competent cells may be acquired from UC Davis, or they could be made competent in a previous exercise.
Transformation efficiency is the efficiency by which cells can take up extracellular DNA and express genes encoded by it. This is based on the competence of the cells. It can be calculated by dividing the number of successful transformants by the amount of DNA used during a transformation procedure.

E. coli transformation: 1 tube of TOP10 competent bacteria is good for the following: (i) 2-3 ligations (use roughly 80-100 uL cells per ligation reaction and add 1/10 volume DNA), (ii) 5-10 standard vector transformations (use 1-2 uL of purified plasmid DNA per 25-50 uL of bacterial cells) , TOP10, and TOP10F Competent Cells, Continued. If you are performing the rapid chemical transformation protocol, it is essential that you prewarm your LB plates containing 50-100 g/ml ampicillin prior to spreading. Cloning Transformation of competent E.coli cells with plasmid DNA.The method for the preparation of competent cells depends on the transformation method used and transformation efficiency required. Cells that have the ability to readily take up this DNA are called competent cells. Although transformation is naturally occurring in many types of bacteria, scientists have found ways to artificially induce and enhance a bacterial cells competency.
