Method
- An LB culture of TOP10 cells was serially diluted and the OD600 reading was taken for each. (UV/Vis Spectrophotometer zeroed using LB.)
- Dilutions were plated out at 10-5 and 10-6 fold dilutions, and colonies were counted using a colony counter to determine the total number of cells in the original dilutions.
