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 we inexplicably didn't see any band), so we cut and purified the bands of interest. Cells harbouring E13 were again inoculated in 5 ml LB + Amp.
After gel extraction, cut DNA was quantified:
