Looking for low copy number plasmids

Overview

Our team faced several problems in determining the copy number of the different iGEM standard backbones available in the registry. We started by trying pSB1A3, and by our surprise more the obtained concentrations of the Minipreped plasmids was higher than pSB1K3. This was the main reason why we decided to compare the copy number of the different plasmids by growin 10 mL of culture until an Optical Density (OD) of 0.6, minipreped it and determine its optical density, as well as, run the samples in an agarose gel.
