IGEM:Cambridge/2008/Notebook/Voltage/OD600 Calibration
From OpenWetWare
Method
- A culture of cells was diluted down and the OD600 reading was taken for each.
- Some of the dilutions were plated out at 10-5 and 10-6 fold dilutions, and colonies were counted to determine the total number of cells in the original dilutions.
