Reactions were incubated at 37°C for three hours; meanwhile two medium-size agarose gels were prepared according to protocols. Moreover BBa_I13521 plasmid purification and quantification were carried out:
In the afternoon gel electrophoresis was performed.

As shown in figure, all clones were positive (apart from E13 run where it is possible to recognize only a band at approximately 2800 bp, corresponding to the undigested plasmid), so we cut and purified the bands of interest. Cells harbouring E13 were again inoculated in 5 ml LB + Amp.
E13 was newly then digested with restriction endonucleases:
